Sturges Can't be killed while dogmeat is attacking him.

[Argyuile]

So while killing the Settlers, I had Sturges down to about 10% life. Dogmeat started attacking him and he healed to full and while he was engaged with dogmeat I couldn't damage him at all. Once dogmeat let go I was able to dmg him again.

I noticed Mama Murphy healed up while I was chasing her around the Museum. Dogmeat was attacking her too. I thought her healing was a feature.

I had something similar with Marcy. Dogmeat was attacking her, so I pulled out my End All weapon and overpowered any remaining HP and it's weird healing feature in one shot. They heal like nobody's business. I guess that's why they lasted so long after Quincy. Bad business that.

Unfortunately, this is not a Conqueror bug, but just a quirk in the way the combat code works. All Conqueror does with those characters, is disable the autoheal, which is an engine level thing.

NICE! I was about to report characters (Mostly Named NPC) auto healing to full as I attack a settlement.
I do use Dogmeat, so Ill try to park him at a settlement.
Glad I don't have to report a bug. =)
