My jet bike fender got all twisted up. Can anyone tell me what I did?

I'm just starting out with XSI and I got Intro to XSI 2nd ed. to learn with. Everything seemed to be going along fine until a couple of days ago when I opened my scene and found my front fender all messed up. You can see it in the attached "First fender.jpg"

This was the morning after I modeled the back harness, so I thought maybe I accidentally selected points and edges from the fender while I was modeling the harness and messed it up myself. So I deleted the fender object from the scene, and started over on modeling it.

I spent a lot of time on this last night and made sure I had it right and looked it over carefully before saving it. It was fine, so I saved it and went to bed. This morning I wake up and open my scene and the fender is all twisted up again (attached "New fender 1.jpg" and "New fender 2.jpg") . Sorry I don't have any shots of what it looked like before, but it looked fine.

Once it is saved it does this? I have never heard of this before. What version of the software are you using?

Yes both times it happened after I saved and exited the program.

I'm using 5.11 Advanced/Academic.

I just modeled the fender again tonight for the 3rd time and froze the object before I saved, and it seems to be ok now. I don't know if that was the problem or not, but someone suggested that on another forum and it seemed to make sense that maybe the operator stack was being applied out of order.
