Levels keep re-setting after being completed

I've noticed recently that, upon successfully completing a level, the Transformer head icon doesn't disappear, no coins/killed pigs are up-dated, and I have to replay the level - sometimes as many as 5 times before it finally registers as completed.I'm on level 111 if that's of any relevance, this has only been happening for the past few days, regardless of whether or not I thank my buddy - very frustrating as I'm finishing certain levels with very high amounts of coins but these don't register. In fact, I have to repair my bots usually so the game is at least registering the damage!!!Any help??
