Those of you experiencing the game crash issues when changing areas or swapping characters and then not being able to log back in, log onto the website, go to my account, security tab, and it will show you still connected. Click disconnect, and it should let you log back in, i don’t know if it will fix the problem, or if it will keep happening if you try to swap character/change area, but it will get you back into game at least.
-EDIT
this fixed my issue and i can now freely move between areas and warp points, or they fixed their log on server, which ever it works now
