Vengeance bug?

Has anyone experienced people you've ressed with Vengeance not dying after the 30 seconds ran out?

I just tried this skill for the first time last night in a party consisting of 1 friend (e/me) and 4 henchman, including Alesia. Twice, I ressed my friend with Vengeance and did nothing else but he never died again. Was it something Alesia did that kept him alive? It was the L17 henchmen leaving Amnoon(sp?) Oasis.

Well, what I know is that if you use vengeance and then use divine intervention... then he/she won't die when the spell end as the killing blow will be negated. Same goes with unyeilding aura + divine intervention.

However... I doubt the hench have divine intervention...

I think I've confirmed that it is a bug and Vengeance isn't killing people like it should. I have yet to see anyone I ressed with it die and then last night in a PUG several people said 'bring vengeance, it's bugged and doesn't kill you.'

I had it used on me once and it appears to not put the enchantment (or hex?) on you that can be removed/wear off and kill you after 30 seconds.
