Sometimes when I switch to another race with SM mode on in the tactical screen I get errors "Function #2947: The given key was no present in the dictionary". The reason I'm not attaching the DB is that the problem is solved if I save, leave and re-start the game and I cannot notice any problems with the game, such as missing stuff. Right now more annoying than game breaking.
The only other thing I can add it usually happens when I've played for a while and from what I can remember it is always a different race that is affected by the errors.
