So far I have seen this on a number of occasions with different PC's
- Elite dwarven guard
- Felar chief

When trying to retrieve I am getting shoved into them, when I flee to track them out and return hours later they are still at the vanquisher.

Initially I thought they were being summoned back, but there was no summoner for the elite dwarf.

Its as tho the palace has some wierd mob rule that doesnt let them track out.

How to reproduce:
- Summon either of these mobs to the vanquisher
- Get shoved into it by an imperial

I have confirmed elite guards track, I have also confirmed the felar chief tracks.
