World Crashes When a Friend Joins

[FireGames26]

My friend and I currently have a world with a lot of mods. After a rollback, it seems the save file got corrupted. My friend couldn’t host it anymore, so they gave me the world file. I managed to load the world on my end, and everything works perfectly fine until my friend joins. When they do, the entire world crashes.

Has this ever happened to anyone before? How can I fix it?

Upload here the master_server_log.txt file from the documents/Klei/don't starve together folder. Also, if any screen with text appear when the crash occurs, upload a screenshot of that screen too.

So, you need to find the mod with the name workshop-2039181790 in your mod folder. The mods are in C:\Program Files (x86)\Steam\steamapps\workshop\content\322330. There need to find the folder 2039181790, open it and open its modinfo, check the name and disable the mod.

If you don't find the folder there, you can search it in C:\Program Files (x86)\Steam\steamapps\common\Don't Starve Together\mods , do the same process

Hmm, that seems to be uncompromising mode. I don't think i can reasonably disable the mod and still play the server. Is there anything here that i can save 😭

I don't know. I think the best thing to do is to notify the mod creator about this bug so he can fix it.

Did your friend use the whatever scalemail uncomp added in their vanity slot? coulda recall scaled armor doing something for you, apparently vanity doesn't spawn lavae from it or whatever and the game keeps dying because the equip code runs every time you load in with an equipment and couldn't find a lavae for whatever it does.

Is there a way to despawn a player before they load in? The world survives a couple minutes after "player has joined" it just dies when they fully load.

I dug around the code myself and i do believe youre right, i just dont know how to fix it. My idea is to despawn the player before they load but idk how to do that.

Backup your save first.
You can delete a player's data by checking the log — in your case, I found a player named Chest Worth with the save folder A7JH7PLMGR4E. You can delete that folder located in Master/save/session/3CC33C980B636557.
Repeat the same for Caves.
You can also create a temporary mod fix while waiting for the official update from the author.
