Three times in the last five minutes I've had bloodbugs refuse to die as a result of being reduced to zero HP while in VATS.

Even if the first hit clearly sends them to zero, they'll soak up three or four more, crits included, and come out smiling. I have to hit them outside of VATS afterwards to make them die.

This is definitely new post-patch behavior as far as I can tell. They've never done this before in any of my previous games. The stingwings I was killing a few minutes ago didn't do this. Is their DOT poison attack healing them? If so, it isn't registering visually on their health bar when VATS is active.

It's just bloodbugs, so whatever, but if this carries over into other enemies I'll get pretty frustrated.

If it's relevant: Level 5, with the tire iron, at Taffington Boathouse.

P.S. Whoever programmed Codsworths response to naming the character 'Anderson' totally deserves a bonus.
