@Littlesimmerguac That magenta circle is usually caused by an outdated version of the UI Cheats mod. So try removing that, and delete localthumbcache.package (again) as well.
Managed to figure it out. it's not the mods, it's the save file that's corrupted. I need to start a new one for it to work
@Littlesimmerguac You could also try reverting to a previous version of the same save:

Losing some progress might be better than losing the entire save.
