Animate guardian reset when getting helm enchant

I decided to run lab to get my helm enchant, where I had my animate guardian located.

When I enchanted the helm the animate guardian dissaperead and also the items it was wearing.

I did not remove the gem before I enchanted (which I probably should have) and it caused it to reset.

Normally I would not bother posting this, but since I'm playing SSF it's a bit harder to obtain the items.
