So when me and my friend were playing and trying to unlock the store at the Plague Witch at the Chapel of Resurrection. I got there first, and the store was available as one might expect.
My friend is not very far in the game yet, and when he entered there was no one there. No store, no quest.
When I tried to accept the quest, we both got stuck in the black loading screen of sorts, though the Merchant and Quest Giver icons were still there. We could not do anything but close the game.
Now, every time he loads into my game, I get teleported back to the Plague Witch, and my screen will be stuck in that same black loading screen.
What do?
EDIT:
Joining my friends' game first and then dropping back out to mine seems to have solved the issue for now.
EDIT 2: 30 minutes of play layer (In Old Villedor at that) we got teleported back. Unable to move, unable to open the map/game menu, only able to open the start menu - Online menu is locked.
Nothing obvious triggered it, but we're not in the black screen now and audio for another quest is playing, that we weren't close enough to trigger.
