Ok, I'll just keep playing for now. I have had the problem several times where as soon as I hit the Sell Fish screen, it closed the game and when I opened it back up, I had to choose which ones to sell again, which ones to get pregnant again, etc.

I have learned that after it closes on me, I must tap the icon at the bottom of my screen that shows everything that has been opened. Then hit the clear at the top. Even if the ONLY thing showing is Fish Tycoon.

When I do that, then tap to play again, I see the LDW screen for a couple of seconds before I see the fish tanks. Then I can go ahead and move fish from tanks 1 and 2 into the Sale Tank, get certain ones left in tanks 1 and 2 pregnant, and then sell the ones in the Sale Tank without having the game crash on me.

But before I uninstalled and reinstalled, it was working to clear the cache for a while too. After a while though, the game would crash as soon as I tried to sell no matter what I did.

Anyway, I have definitely come to appreciate why this has been so hard for you guys to find and fix. Maybe it is Nook's fault, but then it's also the fault of several other Android devices as well.
