No I got the UI, the issue was the yellow boxes not going away.
I tried replicating the issue, no success, I don't remember any specific steps since I didn't do this intentionally.
So the card is exhausted but no angel appears, and the yellow squares still highlight the board... Strange. Definitely a bug, and no idea what would cause it. Hopefully it will just be resolved when I recode that part of the game (the current version was rushed to meet a deadline). Thank you for the report!
