Survival keeps crashing when I win!!!

Over the last few days, when I get to either 1 of the last 2 contestants, Survival freezes and I have NO option but to quit and relaunch losing my opportunities to win. And, most disappointing was 2 recent wins, one of which was about 10 minutes ago and Survival just quit. What's this about? I've been thoroughly enjoying playing it but I'm about to quit because I find no enjoyment in making it to the end and the either Survival freezes or Trivial Crack quits on me.
