Description of the problem

How to reproduce:

1. Attack a wight while it is "possessing" you

Expected result:

The wight either stops possessing the player, takes damage, or dies when it gets to 0hp, and drops experience on death

Actual result:

The wight disappears with no death sound, and drops no experience or other drops
This does not happen every time I attack wights in "possession" state, it is only an occasional occurrence

I have noticed this a lot too. I figured that it just didn't do it's death sounds when possessing. But now that you mention it, your right that they don't drop things either. Never payed too much attention until now.

Happens for me as well.
