Playing on iOS. Encountered a bug with Great Train Heist, not sure if it is specific to that card. My opponent attacked with a pumped Firebending Student and played Great Train Heist, selecting the options for treasure tokens on damage and extra combat. I tapped and held to read each of them, and the combat phase changed to the second combat at the same time as tapping the extra combat trigger UI element. The ability text and card hover-over would not leave my screen and I could not tap on any creatures now hidden behind it. I closed the app and re-opened, and now the card/ability text element was missing entirely, and while my creatures were glowing, indicating that they can be selected as blockers, tapping on them or any other card on screen did not respond, so I was unable to block and lost the game. Some sequence of UI triggers were messed up here, but I’m not sure why. It may be related to Firebending Student’s ability going on the stack in the second combat phase while I was still hovering over the Great Train Heist ability text, or possibly related to having two ability reminders in the left panel selected to view in quick succession.
