I was playing against a boros auras deck and connected an attack with Glissa Sunslayer. I was debating removing an enchantment or drawing a card so clicked view battlefield before making my decision. Then clicked on the creature with a stack of enchantments on it. Clicked out of that and then went back to review the options available to Glissa's trigger. But none were available. Just a blank screen. I roped out and it autoselected draw and lose 1 life which lost me the game.
