Been getting this as well. 3-4 times now in as many days. Last one really hurt as I had gotten REALLY well-geared.

Server resets...I wait a bit for the server to reappear in my favorites list...log in to find my character reset. I've tried logging into another server but to no avail.

It's not just 1 server either, I've gotten this on more than 1 server after a server reset.

REALLY REALLY annoying.
