I don't understand, the module re is imported like 10 lines before line 123. I'll try something in the next bugfix release, but, I'm more than stumbled about this.
For more info: Installing 24.05 and 24.06 can open the 24.04 saved games, play and save them. Installing 24.07 can't open the 24.06 saved game. The same exception is thrown.
