mathmanican Posted June 25, 2020 Share Posted June 25, 2020 I'd love to start a discussion about mass deletion, and have people share links to other topics where they know it occurs. Some of the issues are probably not fixable without radically affecting FPS, while others might be. If we can congregate all our ideas together, hopefully as a community we can help the devs deal with some of these issues. The fix to matter conversion (the good old philosopher's stone) may have resulted in an increase in mass deletion. This thread discusses some of these issues, and @Lifegrow clearly shows how a tiny blob of gas, that is in a room full of another gas, gets deleted, even if the vent has nothing coming out of it. You can read a similar bug report from @DaClown here, where he shows how trapped gasses get deleted by vents. Steam turbine setups that have more than one gas in them will delete steam (for the same reasons as above). This is easily seen in this bug report from @DefectiveNu. Many SPOMs delete mass, which I'm guessing is related to the same issue as all the above. Multigas environments with turbulent flow results in mass loss (which I'm guessing is to avoid a recursive loop that could potentially result from a fix - leading a possible huge drop in FPS). Note that phase changes that transform gas into liquid, when the liquid has less than 10g, will result in the liquid being deleted (liquids under 10g disappear from the game). The phase change also can briefly creates a vacuum tile (more below). I see posts and complaints about mass deletion in steam turbine setups. @sheaker's bug report is where will be placing my comments as they relate to turbines. Thanks for adding a save. Steam can remain at 0.0mcg, creating lots of other problems. Here is one scenario, that I cannot explain at all, and cannot recreate. A couple weeks ago while playing survival, i built a standard CO2 lock to enter the slime biome. After deconstructing some tiles, one tile remained vacuum and the CO2 would not occupy that tile. Instead, the CO2 tried pushing 10% of its mass into the tile every tick, which resulted in a rapid loss of CO2. The vacuum tile was consuming my CO2! I should have taken a video (unfortunately did not), but instead quickly built a tile over the offending vacuum tile, and then deconstructed the tile. The vacuum instantly got replaced by CO2 (normal behavior), and I moved on my way. I now regret this choice, as I lost the chance to snag and squash a rather nasty bug. Note that this survival run was modded, so it may be 100% due to a mod (hence another reason for not putting out a bug report). Anyone else seen this? Has anyone captured it on video, or posted bug reports on it (been looking but haven't see it yet)? I'm looking for more details in my search for steam turbine mass deletion. If what happens in the steam turbine chambers is just another reincarnation of vacuum tiles eating nearby gas, then that would make complete sense. Every time a blob of 2000g liquid transforms to steam, we can briefly get a vacuum tile. If that tile, in one tick, consumes 10% of the surrounding steam, then over time we'd loose a lot of steam. Unfortunately, I don't yet know how to reproduce the bug, and so don't really have a proper bug report to make. Something is going on, and I'd love to really get it fixed. If you want to join the fray, please do. Anecdotal stories, bug reports, massive date collection efforts, save files, memes, whatever, are all welcome. If you use mods, please include that info as well. Link to comment Share on other sites More sharing options...
