Game Crashes During Contracts

I really like the game. The controls are fine, the graphics are great, and the gameplay is really fun. I have had the game for about two weeks now, and it worked pretty well up until about a week ago. From that point on, the game would crash in the middle of contracts, or right as I was about to complete them, which is very frustrating. It happens nearly every time I play a contract. I have an iPhone 6 Plus, so I dont think that it is a hardware issue. I understand that since it is a new game in the U. S., it may need to be fine tuned after release. But, since the game was tested in New Zealand and Australia for a really long time, I spent $5 on what I thought would be software free of game breaking bugs. This bug has made the game unplayable for me, and I would really enjoy playing it. I would rate this five stars if I could actually play it.
