Two succubi NPCs casting charm crashed the game

[bringol]

I had an issue where the game crashed after having two succubi either casting charm on each other or to the same creature. This happened after two succubi spawned in the mines due to me drinking from the fountains. One managed to charm the other succubus, but when they attacked a gnome using what I think was charm the game got frozen and I had to kill it using task manager.
