Ya I'm starting to think its bugged too. I just noticed that the game is not saving after I kick the skull in the net and talk to the red head. But this only happens if I turn the game off and back on again. And when I talk to Heather she acts like its the first time I started her dialogue.
Update: I thought some of the old files might be conflicting with the new version and I think I was right. I had different versions of the game in their own folder all in one folder. After isolating 7.1.1 to its own folder the game saved normally. But I think it auto completed the challenges for me because when I start the zombie map Heather and mac are at the entrance and saying I hit the ball into the net and the "goal!" icon is showing under Annie's picture in the top left.
Moonray Sinkhole seems to be bugged for me though. Still cant complete it and no ball shows up.
