I hope I got the link right, I never use the browser-Gallery, only the one in game:

It happened during my first visit to this restaurant, after I placed it. And as far as I can remember, this is the first time I've had this issue. So yes, only this one restaurant. It is really weird.
This is the first player made restaurant I've had in my game, I've always just placed the Maxis ones from my library. I've not had any problems with the Maxis ones. I'm not sure its the restaurant itself, either. Might be a combination of lot trait and it being placed in Forgotten Hollow, because when I visited the same place in Newcrest, and changing lot trait (when testing), I didn't have any problems. My vamp only grabbed ONE pack, and that was it. He still didn't NEED to drink, though
Did some testing on my save
Placed the restaurant in Forgotten Hallow and placed your Sim into my Vampire household.
Had them both fill up on Plasma packs and went to the restaurant. They ordered and first thing they did after was getting out a pack and drink it .. but after that it seemed fine.
They ate their meal without wanting to drinking again.
Going to tag this as needs info to see if anyone sees plasma pack obsession like that in their game and maybe know why.
Thank you, @crinrict 🙂
I've only seen a sim that obsessed once, usually they will want to drink once or maybe twice. But not every 20 sim-minutes like that first time I visited the restaurant. In my current save I haven't placed any restaurants, and I'm not yet playing a vampire, so haven't seen the issue.
