I've gotten to the point where I am no longer bothering to delete and reinstall. I'm getting several crashes per day now. Running iOS 8.3.

When I do get a crash, I lose all sound EXCEPT background music. So all sound effects are gone after a crash. The only way to fix this is to delete and reinstall. Simply closing the app or hard resetting the iPad does not rectify the sound issue.

But because it's happening so often now it's not worth continuing to reinstall and replay the tutorial missions. The should be a way to skip the tutorials and immediately input your uplay login information. Especially considering how often this buggy game crashes.
