Thank you! I actually noticed that myself. It was accidental at first -- I had just finished moving fish into the Sell Tank and getting the ones pregnant that I wanted to be pregnant and had to get up to do something else so I exited the game. Later when I came back in to sell (without remembering to first clear the Recent items) it crashed. When I went back in, everything was still how I wanted it to be.

I wasn't positive that was why, but after what you just wrote, now I am. Thank you.
