Ack, I'll look into that. Okay, I was able to repro by quickly switching between characters. Will get a fix in tomorrow.
For what it's worth, if anyone else sees something similar - since the game is autosaved, you can always refresh the page to reset things.
There are some clues telling you about the Queen! :)
