Which language are you playing the game in? English

What expansions, game packs, and stuff packs do you have installed? all DLC
Steps: How can we find the bug ourselves? using any method, have a NPC controlled vampire come over to the active lot. Currently the easiest way seem to be to have them as a member of a club.
What happens when the bug occurs? When the vampire gets hungry they'll go through the animations like they're starving and show the icons above their head like they need to feed, but they never bite any nearby sims or do anything whatsoever to feed themselves.
What do you expect to see? I expect hungry vampires to ask for blood, or forcibly bite sims. Or drink from one of their juice boxes. Or something other than just continue to starve.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? Neutral/Not Sure
I was asked to split my vampire thread about a month ago, but completely missed the notifications amongst ones from more busy threads.
When my sims have vampire friends, I always expect them to eventually ask for blood, but they never do, and yet they walk around like they're starving and about to die. This is specific to NPC controlled vampires, but even vampires that are part of the active family and running on free will (no player commands) won't autonomously ask for blood or bite, even when they get hungry.
This may possibly be related to the other vampire problem where vampires come over in the middle of the night and never bite anyone anymore, but not sure.
