I also have this error/issue in my single player game that's causing the exact same issues a LOT, so my game is essentially unplayable. I'm loading way too many mods (I know the dangers and I accept them) but it seems this issue appears to have a fix of "1 Corrupeted Custom Prefab, remove 1 prefab !!!" and maybe some other "fix /repair the map" commands...
I'm totally ignorant in how to do these steps"of "remove prefab and delete chunk map part from server saved folder"..
1. find the corrupted POI(s)... maybe I just assume/guess its the one I'm standing in when it occurs (yes, also my horde base). I believe this is a vanilla POI, but maybe its not as I have compopack loaded, so maybe someone took a vanilla POI and modded it...
2. Remove the POI somehow
3. Do whatever else is needed ("delete chunk map part from server saved folder", etc). how does one determine the chunk?
Can someone link to the commands(s) or steps I need to try to run these fixes? If I lose my game, I'm fine with that I really just wanted to try to fix it if I could and possibly identify the "bad POI's" and manually remove them, regen another map, start over, etc if I have to.
Also my assumption: If the POI is my horde base, I should probably get all my stuff out of it and move elsewhere before blowing away map chunks. what's "hilarious" is I have 2 bases that are in identical POI's (kismet I guess? )... so I guess I have to blow away both my bases!
