Hey Guys,
Think I know whats causing the disconnect bug when zoning.
Character A moves From Server A to Server B.
Server A doesnt let go of the character until after Server B tries to render.
What happens when you try to log into your account when your character is already online? It kicks you back to the character screen. When Server A doesn't release the character for server B it causes a conflict which kicks you out of the game. Then the million retries is the time it takes for the server to say "Oh look their now here I guess I can let them log in again."
So from the things I've tested this looks like the most probable cause of the issue. I will try to submit this as a bug report to Andy and see if I'm even close. But from the way it behaves it appears its a duplicate character logged in at the same time issue.
