I've been having similar things happen to me, Scott!!! I'm not, however, going anywhere to purchase new computer equipment!!!! Since I find that instead of enjoying the games, the inconsistencies and clear "bugs" piss me off, I'm going to PLAY WAY LESS!!!!! I loved it when I first started playing but no longer! The same things happened with my brother and he stopped playing altogether.
I had an instance about a week ago where I had about a 10 foot PUTT, emphasis PUTT!!! The flagstick was still in the hole but I just figured when I hit my putt it would disappear. NOT!!! My putt, which would have gone in, HIT THE FLAGSTICK and veared off about 4 feet to the left and THEN the flagstick disappeared!!!! BOGEY!!!!
