Game rule must be set to enabled, then you can either get lucky from events or use a decision

Does anyone know how to become vampire or a lycan ????

Thanks, I'll add a warning to the description. I don't think I've ever played long enough to see that be an issue; after a hundred years or so the most ai made vampires I've seen was a little over a dozen.

Also, I just wanted to let you know that the reason I put a pretty low cap on AI confer... is because it can get out of hand and cause a ton of late game lag. Especially on lower end machines. So just be aware of that. (Really depends on what settings you run with and how much passing of the traits you let happen).

Appreciate the info, I'll add this in over the next day or so.

They removed these two from the English localization.

offer_vassalization_interaction_aibehavior_dejureliegetitleholder_tt
offer_vassalization_interaction_aibehavior_not_dejureliegetitleholder_tt

I just replaced them with:

offer_vassalization_interaction_aibehavior_rightfulliegetitleholder_tt
offer_vassalization_interaction_aibehavior_not_rightfulliegetitleholder_tt

I just updated my mod and it did require a few tweaks. I've not fixed the localization issues you mentioned here. If you could let me know what they were, it would be appreciated.

Yes I discovered the gamerules yesterday. =)

Nope already has a setting for that.

Please add infertility barren/sterile -250%, vamps dont have human sperms and wombs to copluate with, comon they are allied with death and destruction not some rosy cheeked horny 16 yearold with a tendency to fornicate unless properly married. Hehe
