Bit of a weird problem this evening.
I was playing Approach to Thistletop, and in the Prison location I encountered Collapsed Ceiling barrier.
Unfortunately I failed to bypass it, and, as per the card it became the first thing that any other character at that location encountered. However, from that point forward , even though it was "encountered", no character was able to effect it. The option to attempt a check, or even discard a card, never came up. Effectively removing two characters from the game, as the other effect of the card is to prevent characters leaving the location.
