If upon game launch you are stuck on a black screen with the text
UI Loading at the bottom, this could be caused by mods.
Please follow these instructions to resolve this issue:
- Make a backup of your Userfolder (make a copy of its content)
- Delete everything in your Userfolder
- If you have third-party mods (not from the official repository), uninstall them according to their instructions.
- Verify Integrity of Game Files through Steam
