So I ran into this bug last night, where if you have an ally who is at a location that has a failed Collapsed passage sitting on top of their location deck, and another ally encounters a Goblin Battlechanter (that name might be off, warchanter maybe? Its the one that makes everyone make a wisdom check or not be able to use attack spells or weapons) cause the round robin wisdom checks, when it comes to the ally at the location with the Collapsed passage it wont allow that ally to roll.
I assume that this is due to the interaction of the Collapsed passage. If I exited the game and came back in, it would continue the game with the beginning of the encounter happening and the bug would appear every time. I ended up having to start from the continue and immediately forfeit the game so that I could start a new and not be locked in.
I am on an ipad 4 non retina, using the most current IOS.
I had a 6 person party playing the 4th part of chapter 1 on normal difficulty, no permadeath, no pass and play.
I don't remember the locations, but I do know that the Paladin was alone at the location with the failed Collapsed Barrier and that the Druid was alone at another location that triggered the round of wisdom checks.
Side not, I have noticed a handful of times that some times the Collapsed passage will be ignored and I will be able to just draw the next location card anyway (when this happens, the collapsed passage card is to the right of the location deck and not on top of it.) Figured I would just mention that as I am guessing that this bug has to do with that card.
