Yesterday, I played with The Dragon, the Fairy and the Princess for the first time. We came upon a situation that wasn't completely clear in the rules.
What if there's an almost completed city, with one of Alice's followers in it, and Bob completes that city on his turn, with a Princess tile (which removes a knight from the city the tile is added to)?
Is Alice's knight removed, after which the city's score goes to nobody, or does Alice get the points, after which the Princess has no knight left to remove?
I found an answer which I'll add below, but I'd like to hear your input as well.
