I'm stuck in the prison as well. I'm supposed to talk to Lyris Titanborn, but she is invisible. Cannot progress any further.
Weird thing: It happens with any character I create.
Already tried using /stuck, moving around and relogging.
The game is 100% unplayable!!!!
Looks like they are now where near ready for todays early access.
If its this bad right now i'm really dreading the offical retail launch day on the 4th
