I experienced the same thing today. I'm thinking the problem is with the Guard Tower's at this location effect, since I've never experienced it anywhere else. I got Seelah stuck there, when here turn started Collapsed Ceiling was displayed properly on top of her deck, but after I summoned and defeated the Bandit henchman it was displayed beside the deck and I'd draw the next card when exploring, this happened whether I used Crusade before or after defeating the bandit, or not at all. I don't remember if I ever ended her turn without using Crusade, but I know that when I did use it, collapsed Ceiling would display correctly again.
