I stole an Elven Bow from Aela the Huntress from her room and it's my main weapon of choice now after upgrading it at the grindstone and then enchating it.
At first I sold it to my Theives Guild fence, Tonilia. Then bought it back. That didn't work. Then I sold it to her again and left The Ragged Flagon and returned immediately, to see if a loading screen would make it not stolen.
When that wasn't working, I went to Ri'saad, the cat merchant who fences things for me.
When that also didn't work, I reverse pickpocted it into a bandit then killed the bandit.
When that too didn't work, I put it into a few merchant chests and then went back to the merchant to see if they would finally sell it back, but nope.
Then I finally upgraded it at a grindstone and enchanted it, and renaming it. Then I tried everything again and that still didn't work.
As soon as I can figure out how to get the ''Stolen'' tag off of this thing I'm going to start doing the Main Quest for the first time. This is probably going to be my best bow for several hours of gameplay and I was hoping to make it ''mine''.
