Found a pretty shitty bug.
I finished a match with Jako (gg btw) where I destroyed his crystal. I set my phone down for a few minutes and he rematched me. The game remains in my active games and when I access it, it shows me destroying his crystal and then I get a message saying I lost. No matter what I do from there, the game remains in my active games.
Oh yeah, happened to me too...I had to delete the game as Cheech said.
