As I stated above, we have not been able to reproduce this on our test devices. We will need some additional information from you to help us determine the cause of this problem.

1. Exactly what version of Android OS do you have?
2. What is the exact model of your device? (The more details, the better! )

Here are a few gameplay related questions:

1. Did you complete any research in the game immediately prior to this occurring? If so, which research, and what level was just completed?
2. If you disable sounds in the Options menu, does the game still crash when you sell fish?

The more information you (and anyone else who has this problem) can provide us, the easier it could be for us to determine the cause of this problem.

We do apologize for the inconvenience, and hope that you will help us!
