Hello.
So i finished Mythic Karazhan dungeon (not M+). Just did the entire dungeon solo on Mythic.
Now i got a M+Key for Upper Karazhan, but the problem is that whenever i enter Karazhan dungeon i get ported to the library (after the Mana wyrm boss) and i can’t go back to the entrace to put my key in to start the M+ run.
I tried to reset instances, but it did not work.
What can i do?
Make someone lead who has not done M0. They reset, go in and you can enter.
It’s already reset for him though
Daily lockout ^^
And should anyone else find themselves in this situation, they can see what to do to get round it 
im pretty sure their used to be a teleport back to the midpoint of kz (starting point of return to kz) in the upstairs section of the library after worm boss, how ever it doesnt seem like its there any more.
karazhan m0 is named as “return to karazhan” …
it is in the group finder below all other dungeons … because it starts with “r” for “return” … dungeons in group finder are alphabetical placed…
so there is a karazhan m0.
