Sacrifice and undeads

[Nemhir]

Hi all,
this is my first post on this forum and i want to praise this wonderful game.

I have one question :
if i remember correctly before patch 1.7 (steam) i had the possibility to sacrifice undeads such ghost and vamps but now this option is gone.

It is intended or my game is messed up? I have no mods installed; this will change alot the gameplay for me .

Thanks and sorry for the bad english (im italian)
