So i got the part 2 and Enthir sends me to Mornvunskar. Well there's no one except Sanguine standing there and at first i got teleported to Misty Grove while i tried to get to the chest and locked safebox. So i reload and nothing has changed. No hostile enemies, just Sanguine standing there and the quest marker just points to a stone pillar on the side of the stairs that lead to this big room (where the portal to Misty Groove is). Is there anyway to work this out?

The staff or staffs should be in the Grand Treasure Chest on top of the stair.

The enemies respawned for me but obviously not for you.
