I had about 5000 pounds (yes I'm a hoarder) of items I was transferring from one house to another. I had Lydia carry all of it, and when I took them back from her (I assume that's when, since I didn't realize until a couple hours later) about a good 85% of my items now have a "Stolen" label on it. This is including items that are impossible to steal, like 2 of my 4 dragon priest masks, a dragon priest staff, and dragon bones and scales.
Most of the glitched stolen Misc. Items fixed themselves after I put it in a chest, but nothing else has. Most of it doesn't matter since a lot of the stuff is items I'm going to disenchant. But I'm wondering if I add more legit dragon bones to the stolen stack will the new ones become stolen? And will the things I smith from the stolen dragon bones and scales, and stolen ingots and metal also have a Stolen label on them?

It's a bonus if someone has a "fix" for this... Besides loading an earlier save (like I said, I didn't notice until a couple hours later) and I've done alot since then

I had a similar thing happen when I stored some stuff in the house in Riverwood. My dragon scales and bones were marked stolen and a few other bits like jewellery.
