I thought there was already 2 public instances of LDoN's. At least there was about 2 nights ago. I had my 4 toons on ldon 5 farming for cards to complete CG flag and my monk died. Rezed the monk back with my War and he respawned but on ldon 5 but not the same that my group was in. Was another war at the same camp I did not see in my instance. I had him kill me and rez me back hoping to bet back to my current instance but no dice. Wound up gating him out since he was just there to help with dps.
Anyone - feel free to correct me if I am wrong. But as i understand it. . .
My guess is that the zone crashed while you were in it or you logged in right as the server came up.
Sometimes when these two events occur if someone logs in "too fast" you can beat the server into the zone that has not yet been connected. So the server creates a zone for you to log in - then creates the zone it would have created had you not logged in "too fast."
You are grated a private instance along with anyone else who logged in "too fast." But once you zone out there is no way to get back into that instance of the zone.
