Often enemies don't die, they just go into bleedout

[Mrod23]

This is a new one for me. It seems some enemies recover health so fast they never get to zero, but they do go into permanent bleedout. They stop fighting, of course, but if it is a boss the quest won't clear.

 

I've tried all the console tricks I know, such as prid = xxnnnnnn: playidle bleedoutstop, ResetAI, kill, etc. and nothing works. If I resurrect the bad guy, he/she pops up and then drops into bleedout again.

 

Any ideas? Anyone seen this before?

 

Cheers
