Edit: Login bug still happening despite my best efforts, i musta just gotten lucky a few times?
This bug apparently doesnt happen to everyone, tho i have gotten it many times on 3 different computer, basically the first time you attempt to log in the game crashes.
Ive found that if i select another character at selection screen then select the character i want to log on with the game doesnt crash, so far its worked 100% of the time since ive started doing this.
While messing around in character selection i found that if i switch characters right when its loading avatar onto screen that i can have one character selected while it displays another characters avatar, this MAY be linked to the bug somehow. When this happened i had to select several different characters before it started selecting correct avatar, so theres some sort of mixup in the pointers(records, fields, not sure how they have it set up), possibly causing the crash, hard to say.
Has saved me a few minutes since i started doing this, that and occasionally the crash is bluescreen, so could harm windows and needs to be avoided.
