Ideas
Hello, I am also having this issue. I repaired my game, deleted mods (even though i disabled them months ago before this happened), as well as moving the households out of newcrest. Originally when I was looking at the files, there were quite a few lastexceptions but I deleted them, ran the game again, closed it and it threw one last exception "lastUIexception".
When I open the lastUIexception, it says this
