Incenerator of the guilty
My opponent played incinerator of the guilty against me and ended giving me a loss, because it got stuck with no evidence to collect and timed my opponent out and then went to my turn and timed me out because the collect evidence was still on the stack on my turn. The interface wouldn't let me even conceded the match. I'm guessing the same thing was happening on my opponent's end. You should put an option for the player to back out of the desicion to collect evidence because even my opponent trying to select 0 for x wasn't working.
I'm was using the mtgarena app for android. I used the capture log feature when selecting to report a bug on the app but I can't locate it in my files on my phone.
