Happened to me twice, only on the second time, did I think maybe it’s a bug.
specs:
Ipad model number: MP252LL/A
event:
won fight with all three characters alive, two unused. Doublicious waited in victory for about twenty seconds and then the next bit loaded saying I lost and can pay 135 theonite for my streak back. Wasn’t given the option to retry or this will be counted as a loss if you cancel. It just loaded my loss screen after I won.
