I looted these bracers last night in a public dungeon, from a locked chest. A while later, I opened my inventory to discover that they were showing up as stolen. That was odd.
About 10:30 pm PST I went to the fence and was unable to launder the bracers. I tried selling and I was unable to sell them.
I logged in this morning, same thing. As you can see in the screenshot, I haven't fenced anything during this 24 hour fence period - and neither have I laundered anything.
This happened to me a couple of days ago with a different item but I can't remember what the item was, only that it was a piece of gear.
