One of my followers disappeared?

So I had a massive following in my cult. 56 at the highest when I checked. It completely fucked up my game and crashed/softlocked me twice. I started going on a mass murdering spree to try and cull it, and everything seemed fine, but when I tried to find Hauras (who became a favorite of mine) he's no longer in my list of living followers, and when I go through my list of dead followers to resurrect, he's not there either. There's babies with his name as one of their parents now, so I guess he's not completely removed, but I have no idea where he's gone.

Edit: Nevermind, apparently he dissented in the chaos.
