I don't think it was stuck until after the iPad auto-timeout/lock/screen sleep (e.g. sometime after waiting for me to discard for damage).
Where can I read more about the iPad bug?
Do you know if I can resolve the issue myself (or edit the save game file)?
Hopefully, I can salvage my characters/party. I only had 2 in this story, but the rest of the team have pretty decent B/C/1 cards.
