Capturing a Queen

I'm going to star this off by saying: This is my very first first subterfuge game, so correct me anything I am wrong about. Subterfuge is the most fun game I've played in a LONG, LONG, time.
Here some background for the game: Normal 8 player FFA. Two players resigned in the pre-game setup time. Now it's a 6 player FFA. I captured one of the resigned players queen and instead of it becoming a princess like she's supposed to, the enemy queen is captured in the outpost and I can't do anything with her.
TLDR: A player resigned, I take thier queen, and it didn't become princess, it is just sitting at my outpost captured
