More info in case it helps. I had been playing Game of Death (Madness, manual, 1x) when it was crashing. I decided to start farming Point of No Return (Hard, auto, 2x) just to try and get as many trooper badges as possible despite the crashing. I actually made it through probably about 120 sands worth with only a handful of crashes.
I tried Game of Death again (Madness, manual, 1x). In four matches it 1) crashed at killing blow, 2) made it through the whole match but all end match animations were really slow, 3) crashed at start of match, and 4) crashed at killing blow. Went back to Point of No Return (Hard, auto, 2x) and did four matches so far with no crashes.
