In the vault among the items I stole were Glass Greaves and a Glass Left Pauldron. Now, from here I went to Ghostfence to the guy that sells glass armor. Luckily for me, he had a full set of glass armor for sale (Including the Glass Tower Shield). I first selected to buy all glass armor pieces from him and then sold what I needed from the Redoran Vault to break even.
Now, even though I sold the stolen Glass Greaves and Left Pauldron, the game still flags the Glass Greaves and Pauldron I bought legitimately as stolen. I'm sick of guards confiscating Glass Greaves and Left Pauldron every time I get caught doing something.
I read this on UESP:
An unusual quirk of this rule is that it applies to all items of the type that you stole, even if you get rid of the stolen ones and acquire others legally.
Are there any mods that fix this?
