I was one of the people who came across the unstick me bug that warped you to the new islands. My buddy and I took our chance to explore and came across some rings. These ring were later taking away from some accounts but not others. When I logged off and back on I was stuck and I couldn't move or access my items. So that sounds like a very bad bug to me.
Oh yeah, I used unstick me and got stuck again with a few other people, who I'm assuming also had the rings.
