Roughly the same thing happened twice to me today in that a Turf War game crashed just as I was putting for the win - when the app rebooted it went back to home screen as if nothing had ever happened! On checking the Turf War leaderboard no coins were credited against my name to the club score - no idea if my entry fee was debited as I never count my coins...
No wonder most people I know only ever play the lower ranked Turf Wars and just lose to the Tour Pro pirates playing off the forward tees with better clubs than we have...
