IPad Air, forget which IOS version.
Was doing Black Fang Dungeon Heroic, Wild card power was "Blood in the Sand" (Discarding >1 card to damage forces you to bury one of those)
In the "Desecrated Vault", on her first explore of the turn, Kyra encountered a "Pit Trap" and it showed a "-1" to her roll. I tried multiple stats, and they all had it. If there was some legitimate in-game reason I was supposed to have a -1, I couldn't figure out what it was. So I assume it's a rules bug.
Attached is a picture I took of my game at that time.
