I fixed it by throwing bodies at the shelves to put them back in their original position. Then to get the npc to spawn i exited the animus and then entered again the guy was there.

So i had both bugs. The one where the shrlves would spawn on top of the jars and the NPC not appearing. The workaround is first you put the shelves back in their original location. If a shelve is stuck, throw a body at it to move it. Then i left the animus and returned the guy spawned this time on the outside of the building and mission was complete.

The Demon Odour at the Tithe lunden mystery does not work for me.

This is the series of events that led to it:

1. I entered the warehouse before the final boss mission in Lunden arc and broke the jars and moved the shelves. At the end there was nothing and moved on.

2. After defeating the boss of the Lunden arc the mystery appeared on the map. So i went to the warehouse.

3. The jars respawned but the shelves were wher i left them. The character that you need to get out was there and i spoke to him. I removed all the jars but one of the shelves spawned on top of the jars and outside the moving area which led to me being unable to move them to the right position to trigger the guy from leaving.

3. Because he did not leave i decided to spawn to a viewpoint and then go back to try a different approach. But now the mission character is gone.

4. Tried different times to spawn back and repeat. Tried moving the shelves back to its original location but nothing works.

5. Apart from that 1 instance the guy hasn't spawned back in.

Please fix this issue.
