Kaz's house is also causing my game to refresh on my iPod. I can do everything else, just not try to collect on Kaz's house. Up until now I was getting Trolls appearing when I harvested mushrooms but since the problem with Kaz's house I am not getting them or any 'beastie' at all. I hope this problem is fixed soon because I only need to fight 1 more troll to move onto next level.
