Kingsmarch "Door" in the Azurite Mine leads to game crash/disconnect

I have found a bug, that creates a "Door" from the Azurite Mine to Kingsmarch. If you try to use it, you get disconnected.

To create the "Door", you first have to be in Kingsmarch. Then type "/delve" to teleport to the Azurite Mine. If you use the waypoint it doesn't work.

Same for when going to the Monastery of the Keepers. Kingsmarch portal there also keeps disconnecting me out.
