Oh I will do more testing.

for some reason this mod makes vampires have script errors and reset endlessly when in vacation worlds.

Oh that's weird. I haven't had this happen to me. Do you have mods like traveller? I use it. Wonder if playing without traveller's causes problems. Maybe it's due to how seasons work with vacation world.

yep traveler fixed the problem. admittedly i tend not to use traveler unless i have too to load into vacation worlds, and on the flip side for some reason it outright prevents me from loading into oasis landing so i always have to make a point to remove the traveler mod when i want to go there.

Traveling to future has worked out for me via the time machine. Maybe that issue is fixed now.
I think since my mod checks for weather and I think without traveler weather doesn't work in vacation worlds that's what causes the glitch to happen.

does compel to drink interaction have any sort of fail chance depending on your vampire skill?

No. But if they are already compelled to be someone's servant then it can fail.

First of all, thank you for this amazing mod. I always liked vampires but I was a little disappointed at certain aspects the sims 3 vamps are definitely missing... which this mod fortunately added However, it seems I'm missing the turn into vampire option with this mod. I was initially looking for it between the vampire and his significant other, a witch, but I can't find it (I used master controller to set the vampirism ability to 10 to see if that's the reason). Next I had the vamp compel a random human sim from the town to become his friend, still the same, the option is missing.... any ideas what's going on?
