[Game Update] - Public Testing - 658361

[JarrettM]

Hi everyone, 

It's time to start public testing for our March 2025 Quality of Life update!

This free minor update contains a variety of bug fixes and quality of life improvements for all versions of the game, including some DLC-specific additions and improvements. 

Highlights: 
We've improved searchability in the build menu and Research screen, as part of our ongoing effort to make it easier to find the buildings and technologies you're looking for. 

Liquids in the world now provide more visual feedback for temperature changes. A baseline level of mild "underwater"-type distortion becomes increasingly conspicuous as the liquid's temperature rises, eventually leading to bubbles that intensify as the boiling point approaches. We've also changed the way that liquids get displaced in the sim, to fix some liquid duplication bugs. If you spot any issues related to this, let us know.

Some of the fixes in this update include: Flydo bugs in The Bionic Booster Pack (including one where Flydo was displaying erratic autopilot behavior upon depleting its power bank supply) and several systems in the game now use fewer memory allocations per frame. 

The Bionic Booster Pack: the Skill screen for Bionic Duplicants now contains an overview of boosters that are available in the world, as well as the ability to assign and unassign them directly from that screen. Bionic Duplicants are now susceptible to diseases. 

If you discover bugs or have any feedback for us, ping us here!

Thank you so much for helping us test these changes! 

Here's what you'll find in the update so far:

  • Fixed an issue that could happen when launching the game on Macs, when installed on a non-native file system such as FAT32/exFAT.
  • Fixed an issue where an Incubator whose egg had recently been removed would request the egg when loading the save again.
  • When the power circuits are rebuilt (e.g. network is disconnected or reconnected either via construction, destruction or circuit breaker):
    • The current load on all circuits is now set to an invalid value (-1)
    • the wire sidescreen will display this state as "?"
    • the wattage sensor will now not change its automation state until it receives a valid value from the wire it is monitoring.

Supply Closet

• Frosty Planet Pack
  • Added The Frosty Planet Pack-themed cosmetic blueprints for monument parts.

Modding

• A significant refactor of the DLC system was made. Attempts were made to prevent mods from breaking, but some will need to be updated by their creators.
• Deprecated supportedContent in mod_info.yaml, instead use requiredDlcIds and forbiddenDlcIds.
• A large number of methods were marked [Obsolete] with descriptions of what to switch to. Please check your warnings and turn on warnings as errors.

• IBuildingConfig implements IHasDlcRestrictions.
• ComplexRecipe now supports forbiddenDlcIds too.
• Added IHasDlcRestrictions to a number of other classes.
• Deprecated all SaveLoader DLC methods. Added static methods to Game for checking DLC state of the current save; use this instead.

• Mod screen:
  • Added tooltip explaining why a mod can't be loaded to the mods screen.
  • Added tooltip to mods on the mods screen to display their description defined in mod.yaml.
• Changed codex yaml DLC checks to requiredDlcIds and forbiddenDlcIds (previously it was dlcIds and forbiddenDLCIds).
• FileSystem ignores filenames starting with "._" (AppleDouble format)
   

What is public testing?

"Public testing" means players get to test-drive new content early and give us feedback and suggestions before it goes live. Because this is an unfinished and in active development version of the game, it's pretty likely you'll encounter bugs, crashes or balance issues while playing these builds. We'll try to fix any problems that crop up as quickly as we can, but it's possible you'll lose progress in your games while playing on the Testing branch.

Regarding performance, the Testing branch has additional debugging tools enabled to help us track down crashes. This makes the game run more slowly than the live version of the game.

Please also be aware that once a save is loaded in the Testing branch, it cannot be reopened again in the previous Live branch or previous builds.

What do I do if I find a crash or a bug?

Post it up on the Bug Tracker and we'll fix it as soon as we can. If you can attach a copy of your save file to your report, that helps us even more as we can pinpoint the source of problem more quickly.

Do I have to play the public testing build?

Nope! If you'd prefer to only play a stable build, you can continue to play in the current Default branch until the game launches in full. Playing the Open Testing build isn't necessary, but it helps us a lot to receive your feedback and reports - if you're interested, try it out!

How do I become a public tester?

There's no sign up or registration for becoming an open tester. If you own Oxygen Not Included and want to join the Testing Branch, all you have to do is play the Open Testing build on Steam.

How do I play the public testing build?

You can switch your branch on Steam using the instructions below:

Spoiler

How to change branches in Oxygen Not Included (Steam)

Pleased to see lots of ancient bugs getting fixed! Does this mean no more accidental exponential liquid duping for liquid storage?

Heh IHasDlcRestrictions

• Fixed a bug where liquids on special tiles such as airflow tiles were being displayed as if they were floating above them instead of sticking to said tiles.

That was a bug?! That's been in since the tile was added I think. Why now? Huh... Not that I will miss the effect cos I hated it but, now?!

Because Daniel is a machine and when his hopper of work runs empty for even a moment he doesn't idle, he demands that ancient bugs be fed in! Right now he's fixing some rendering bug on linux that's so minor I barely noticed it.

Hurray!!!

I'm not sure I'm gonna have the time to play this week, but all of those fixes look very nice. Thank you for the QoL <3

You mean shine bugs generating light "shadows" across the screen?

[Tigin]

Although we won’t forget sublime liquids on airflow tiles, we have a worthy successor!

This sounds different than the bugs we're looking at, could you post a screenshot?

Pretty cool visual feedback for heated liquids! though i noticed that there doesn't seem to be any for the inverse, when a liquid is about to freeze. would that be possible to implement? Would be nice to have congruency in this aspect, and a bit helpful too!

Do you one better, streaking is noticeable through levels up to a certain point (it doesn't cross all the map) :

 

 

On a separate note, a bit of artifacting is occurring on some liquid locks...

 

 

Pacu don't mind, tho ...

[Vertel]

Love the new FPP blueprints, but the names/descriptions on them don't seem to match up with the piece. Freyja's head has Liam's description, Pei's has Freyja's, etc., and this holds for the midsections and bases as well.

This would be fantastic. Maybe small crystals floating in the liquid, appearing and disappearing.

And not to flood the post with replies, but this patch would be the perfect time to fix the bug of Natural Gas Generator CO2 emission not being properly clamped to the building temperature. There's exact details of the bug and exactly what code needs to be changed to fix it in this bug report. https://forums.kleientertainment.com/klei-bug-tracker/oni/natural-gas-generator-not-producing-output-at-the-correct-temperature-r43070/

Updated Solid Crude Oil tile and ore art.

solid Petroleum and Nafta still looks like a Wolframite

Not sure to understand, does that mean infinite storage is gone ? Or it's just a visual and meant to adress the liquid duplication thingy?

Infinite storage is still around. This is purely a visual change. The change to how liquids displace in the sim doesn't stop infinite storages working; it just makes storages a little more stable and prevents liquid duplication.

Much to my gratitude, thank you yet to the chagrin of many others. He will be both loved and hated for it, Im sure of it!
Thank you for the reply as well. Please pass my "beep, boop" to him  Cheers!

Its still can store infinity of liquid, but now it cant generate new liquid out of nowhere. So no longer 1000000000000000 kg per tile...

[imazined]

Nice changes. But I hope we get a better hot liquid effect because this one hurts a little bit to look at if I'm zoomed out further. It looks like moire noise.

And it's way to even. The hot air effect in comparison is much more subtle.

Does it look better in a more natural setting when there’s a temperature gradient?

Idk. I usually have 95C water tanks over the long time

It looks like that at 95? Seems too low to me. Maybe the distortion effect is ok at that temp but imo the bubbles should only show up above 100

[kurosolo]

So I tested how some liquids behave after the patch - they start bubbling once their temperature hits some threshold, and those closer to the boiling point have clearer bubbles. The bubbles resemble what the liquid would boil into, so "petrol" bubbles in hot crude oil/gunk. That should be why some bubbles are barely seen even when the liquid reaches the highest temp possible, such as liquid sucrose/visco-gel/phyto oil/etc.

Approximation of the temperature threshold when liquid start bubbling:

Water, 87°C

Magma, 2220°C

Liquid hydrogen, -251°C

Crude oil, 332°C

Super coolant, 340°C

My best guess is that the temperature threshold T is actually tied to their liquid temperature range (actual boiling point T_b minus actual freezing point T_f).  The ratio (T - T_f)/(T_b - T_f) seems to be 0.85, however my eyes are not sharp enough to tell.

Also I've noticed that some liquids look more gray when approaching freezing points, which the notes didn't mention. Water < 3°C or magma < 1450°C should be the example.

So does this mean it's no longer an automatic death sentence to dupes? (other than using exploding rocket therapy to reset them)
