Was playing a match on IOS, I had Lord of the Uvenvald in play, I attacked and chose green mana, opponent used wandering emperor to exile my creature on the stack, in response I used moonragers slash to kill the wandering emperor, and when the stack resolved it got stuck on the lord of the uvenvald trigger and I couldn’t click or do anything until the game roped me out and passed my turn, despite the fact I had plenty of mana, two creatures in my hand, and a whole second main phase I hadn’t taken yet. This bug made me lose the game, very infuriating.
