Hi! I have been trying to solve this exception alert and cannot find the source of it. I have no mods, tried removing cache, and repaired the game. But this same exception comes up every time I play ...
Ideas
BE is also a mod, so you need to remove that as well.
After doing that, please delete all the lastexceptions, lastcrash and localthumbcache file.
Go back to your game and trigger the error again.
Check the documents folder for new lastexceptions. Open that with a text editor and copy/paste the content to a post.
This is the last exception.
