I had a crash yesterday on my Palm Zire 72 - it was when I accidentally selected "Beam" from the main menu (I think). There was a fatal exception, and the Palm had to reset.

When it loaded back up again, 2 of my children had different names, the vilagers re found the lagoon, and I was back to Level 1 science, but had the points to buy Level 2 again. My food level also dropped drastically.

Today, while it hasn't crashed, I have had some weird pixellating with some of the characters. They will moved in blocks and leave a blurred trail.
