refilling NPCs

I think I found out what decides if an NPC refills the bloodpool on the next mapload.
Seems, it depends on the NPC class.
"npc_VHumanCombatant" does not refill, but "npc_VPedestrian" does.

Is that why I don't lose humanity if I accidentally drain a thug? I'm always doing that because, well, I noticed that they don't refill. Never crossed my mind that it was because they were combatants. I always figured that it was decided on whether or not one is in a combat area or if the NPC in question was aggressive.

I'm learning so much here. *wipes tear*

It seems to be that way. I only found out now, while I was trying to make Venus a blooddoll. Haven't done tests yet, but since the people who don't refill usually are guards or thugs...
For the humanity, I'm not sure. Afaik, in a masquerade area, you should loose humanity even for killing combatants, unless they attacked you first.
On the other hand you can always stealthkill hunters. But they are set hostile from the start.

Venus a blooddoll? I like that idea, because the single useless Seduction line you can use on her always annoyed me.

I've done it often without losing Humanity and it always puzzled me. Might be a simple glitch, since I can't be sure I never lose it. I've even had a thug attack me for no reason and found that he was low on blood when I attacked back.
