I accidentally moved Seoni to the Throne Room (where the Villain was) instead of the last open Location, the Temple. So when it came to Ezren's turn to put the Villain down, I used Haste to move her to the Location I needed closed. I'm prompted to pick a card to discard (normal behavior for the temple) but when I do, the "proceed" blue arrow on the right is greyed out and unusable. If I shift to Ezren, the arrow is bright blue, but clicking it has no effect (since it's Seoni that has to discard, not him).
It's impossible to do the Discard I have to do, and it's impossible to cancel the spell. The game is locked and I can't do anything. Especially infuriating considering that this was the last turn before an easy victory. Please help, I can't even keep playing my game.
My handle is Sojiro888 #1854, the mission is The Black Tower (4-3) on normal difficulty. The team has 6 characters: Seelah, Kyra, Merisiel, Harsk, Seoni, Ezren.
