Hey, are you trying to continue on the same save file? Once a mod installed unfortunately they will permanently alter the save file. You need to manually remove the mod files from the game files, verify the integrity of the game files and try to reproduce the issue on a new, unmodded campaign. Please have a look at our clean install guide to see if you have missed some steps while re-installing, and our
common workarounds list to see if any of the steps in there will help with the problem.
