Make sure all the characters in your city names are english characters. Any non-American letters (like letters with accents or tildes) will break the BUG menu. As for the Automated Promotions for units, check that you didn't turn on the automate promote option in the game menu. Hit Esc, go to options, and check that Automate Promote is off. Also, check that you didn't select auto-promote on each unit. 99.9% of bugs at this point are user error.
