No, some dungeons are just problematic. I can run some dungeons all day and never see a single issue.. then I load the Raven or Powerslave.. and I'm lucky if I go 4 runs without a crash or problem.
I think.. and I'm completely speculating.. that it's the dungeons with 6 enemy lineups.. so many graphics going on at times with 6 enemies... that the app crashes or freezes.
