I've been trying to fix this for ~4 hours and have tried these fixes:
- Restarting the game
- Restarting my PC
- Reinstalling tmod/fully resetting than reinstalling
- Went through every mod 1 by 1 seeing what was the issue (none were)
-Unlinking onedrive
-Verifying gamefiles
I'm pretty sure that there's something with my world file, seeing as a different world with the same mods did save without crashing.
