Server error in Caves

[Cheesecato]

Hi, searching high and low to salvage my 10k-day server.

I was wondering if anyone could help me find the problem. I asked chatGPT and it seems like the recent updates of the game messed up the portal system that I had
with the old lazy deserter mod https://steamcommunity.com/sharedfiles/filedetails/?id=914857246  Hence, corrupting the caves file.

If I delete the caves file, almost everything that I built on the overworld disappears. I'm all for resetting the caves, but not the overworld. Is there a way to do this?

This is the caves log attached.

I would appreciate it greatly if someone could help as it is sad to let go a world that I've played on for 5 years +

The incompatibility more than likely has to do with this mod. https://steamcommunity.com/sharedfiles/filedetails/?id=1505270912. I confirmed it when attempting to generate a caves world with that mod and got a similar error.

vaultroommanager is a new component added in the recent Ancient Echos update that's responsible for adding the hidden archives biome (idk the proper name). It probably can't be retrofitted properly because From Beyond notably generates worlds in an unorthodox way (though I'm not saying definitively this error is the fault of the mod). As for a fix, you would probably have to disable the vaultroommanager or find what's causing the markers not to be generated in the mod specifically. I have had difficulties working with the From Beyond mod, so you may find the second solution difficult.

Thanks for the reply!
To note, I have not downloaded TE mod in my server. If anything, the closest thing I have would be Kyno's Heap of Foods mod.

Right, it seems I confused the mods. That sounds about right.

I heard "Too Many Items Revisited" also caused similar issues, as well as API Gemcore (but you don't have that on your server). My guess is the Show Me mod. Give it a try without it (but make a backup of your server before)

Hi, thanks for the reply, so currently, I have tried taking out every mod and launching the server, which was unsuccessful. So I do think it's the new "vaultroommanager" implementation that is causing crashes.

Well.... that sucks

It doesn't look like you have any "problematic" mod on and turning off Heap of Foods would also just remove any content related to that mod which is suboptimal. (and i didn't hear about that mod causing issues with retrofitting.

I wish i had any good tips for you but i don't know how to force skip retrofitting on a shard (cause you could spawn in the Vault once the server is up).

Maybe try making a new server and switch out the old caves with the new one on you server and start it. If it starts like that, switch back the old caves and see if that way you can start it as well. As always, make a backup before

Sorry for the delayed response. I was preoccupied.

Try downloading and extracting this in Steam\steamapps\common\Don't Starve Together\mods

vaultroomhotfix.zip

in Steam\steamapps\common\Don't Starve Together\mods\modsettings.lua add this line:

ForceEnableMod"vaultroomhotfix"

Let me know if this changes anything or causes the same error. it worked for From Beyond and Heap of Foods (or it seems to work?) and that's all I really have to go off of.

Also if this mod still works, try it. https://steamcommunity.com/sharedfiles/filedetails/?id=679848538

It's possible it would give a better clue of what the error is.

Also if you're willing, sending the world file might help. The error might be too specific and I have to address the error caused by vaultroommanager more directly.

Hi, I did try the above things and just wanting to make sure if this is what I was supposed to do:

This is my server file, Cluster 1 is the server that I'm having trouble opening.

Great news! I was able to open the server with the fix enabled! It seems like I was struggling in the process because I had multiple saves that didn't sync with each other. I erased the unnecessary ones, and now the server is back up with all my things intact in the overworld and caves!

I didn't apply the 

ForceEnableMod"vaultroomhotfix"

to the modsettings.lua file yet, but it is running and now I'm wondering if I should do this extra step as well. (on the side note, does it not need any brackets?)

Thank you thank you so much @Oregu! I send you my respect and love!!

It's strange if it was fixed without that ForceEnableMod line being in the modsettings.lua because that's the only way that mod can possibly run (to my knowledge), so my mod may not have been what fixed it. Also the way that lua's syntax works is the first argument to a function can be formatted foo"bar" if the only argument is a string. I'm glad that a solution was found, however.

Oh this is strange. I took out the fix from the mod folder and my server still runs fine with the vaultroom still active. So somewhere along the way I'm guessing it was because my save files were not aligned while fixing one of the mod files manually...? I'm not so sure. I fixed the Fueled Lazy Deserter https://steamcommunity.com/sharedfiles/filedetails/?id=914857246 in the midst while trying to fix this problem, maybe it was solely due to this mod, but my save files were de-synced.
Regardless,  thank you for your help, I'm glad I didn't give up after your reply!
