I've been mapserving a bit too much recently, I think /my/ problem originated with I20. Before this I was fine. I was not able to log into the game for a while since I was away in vacation, I came back (march 27th) and started playing around the time it came out. I was in a TF and within an hour, I got mapserved at least 7 times. It got extremely frustrating. A day or two ago I got mapserved, logged back in, and just as the zone had loaded, it mapserved me again. At times I've been mapserved in the character select screen, before I even click on any character.
I have no idea what to do or what really is causing this. I've been mapserved in cimerora (which is not really a surprised considering), Eden, Founders' Falls, Independence Port and Steel Canyon so far. (I haven't been much to other places.)
