I'd forgotten about this thread -- sorry!
Just an update: The lovely neko had been logging in and out fine despite her doppelganger being stuck on my land. I told her if she wanted to see something really disturbing to come back, which she did! Not long after her doppelganger disappeared. Not sure if my neighbour contacted LL, or if she did... but it's all clear now! She was incredibly apologetic and I told her not to be (gave her some Japanese neko art).
SL can be a funny little creature some times.
Now where's the tuna... someone mentioned tuna... ohhh yarn... pretty string... shiny...
bat bat bat...
