I usually don't have any issues with crashes, freezes or missing buttons. But I crashed twice against this GAC defense team, first with JMK and then with JML. Same situation in both cases: Canderous and RG down, Maul almost dead, 2nd Sis alive and well. LV uses ultimate and bam, "Unfortunately Heroes has stopped."
It's especially annoying since this is the last team in the territory and I had a great chance of winning this round. No crash when I followed up with SEE but of course I lost. My ally code is 385-516-646 in case someone up high wants to look into what might have caused this.
