Poof, it's gone

We were exploring the fire giant caverns with Valadiren and when we turned back, on the way out, not far from the entrance, my axe just went poof, and was gone. It wasn't in the battle, but rather after battle, which is the weird part in it. Also, it wasn't after the commander spawn (he can disarm weapons) either. I even took a screenie, check it out:

1. Battle was over.
2. That's the point where the axe disappeared.
3. Lost item proof.

The axe was nowhere to be found in the ground.
I would like to have it back, of course, if just possible.

Another bug I'd like to report is that there's a "Huge spear" in dagger falls general store with 1d8 extra piercing damage. I don't think it's there for purpose.

I'll try and catch you ig.
