I choose puppet city, city instantly starved to one pop, and never begins to build anything. I investigate and find it's not even working the city plot! Reload to just before the peace deal and it happens the exact same way. I reload once more and this time refuse his peace offer only to turn around and offer it right back to him on my turn. He accepts, I puppet city, and city behaves as expected. You can see the bug unfold towards the end of part 1 of my Warring Washington series here. And me working around it at the start of part 2 here. This isn't a fluke either. I one time had received a city (can't remember if I conquered or got it through peace) and puppeted right away. I reloaded that same turn only to find the city had been auto-annexed. Any ideas on what might cause these cities with identity crises/getting stuck in limbo?
