I noticed similar threads about this, but thought I'd put my experience in.
Cravens Walk.
Would be sneaking arround like a good brigand should and would see a potential mark.
Would open up with a bow attack, thus bringing me out of stealth mode.
While the furious mob would be charging to me, I can usually finiah a HO on it
If im lucky, maybe even another CA attack.
When the mob finally hits for the first time, bang! I've feigned death, the encounter is broken and the mob is re-healled.
I have bugged this ingame several times, but it is broke and needed to be added to the list.
