Need help, mods are bugging out.

sooo around 2 days ago i was playing modded lethal company with my friend, everything worked fine and we had alot of fun.
but then when we decided to play again, for one reason or another modded moons were glitchin' out, whenever one of us chose a moon we would get another moon (what im meaning is whenver we would get a different moon on our side, example: if my friend chose atlantica i would get ether, if i chose atlantica he would get orion. though strangely enough vanilla moons worked just fine?)
today we decided to play again, maybe it was some sort of glitch that could easily be fixed by re-entering the game. nope! it was still there
we tried reinstalling the mod collection and reinstalling the game, but nothing worked. i thought maybe the mod collection is completly busted, so we installed a new one!
guess what, it happened again. we joked about us having a curse of corrupted moons so we just played on vanilla moons
until it got EVEN WORSE!! the modded and vanilla interriors started ALSO bugging out! (example: my friend got LC_Office and i got mansion.)
after that happend we completly gave up and went vanilla

i suspect it had to do something with either thunderstone modmanager or bepinex, but i'm not sure. any ideas?
