Basically I'm going to make this thread to sum up the info we got about this bug in a hope devs can fix it ASAP.
>Only affects characters who are in a guild (not 100% confirmed)
>Get you stuck on a "Heading into Haven" Loop when trying to chose a affected character
>Sometimes (rare) it let's you in the game but won't let you change Havens, go down the clockworks, etc.. Also, if you log off you'll get stuck again.
>You can still create another character in the affected account
>Getting kicked from your guild FIX the logging problem
