Please fix this problem.

The iPod Touch is the perfect venue for this game because I can take it with me in a way I would not wish to do with my laptop, but twice now, after upgrading my environment, I've gone into the application to find that my fish are just gone. Not dead, but gone.

I just can't afford to spend time playing if this is going to keep happening, and I definitely can't afford to pay for the full version if this happens on it as well.

Also, I have not changed my system clock in order to make the game speed up.
