UNBELIEVABLE - My Cart is Randomly Deleting Stuff

I noticed about a week ago or so that I was missing an attribute on one of my products and thought little of it. I just re-added the attribute and went back to business. Today I got to wondering why in the world I haven't sold a Condor PS1500 Wheel Chock in a while so I went looking for it on my site and it's gone! I'm the only guy who runs my site. I can't imagine who, what, when, why, or how this is happening. The damn database is just randomly deleting my work here and there. Please tell me you've seen this happen before and you know how to fix it?

I've added the missing product back in place now. But I've still got to figure out why things are disappearing?

You didn't mention anything about applying the important security patches for v1.3.8a. Maybe you've been hacked?
Either way, you should be planning an upgrade to the more secure latest version.
