Last time I tried to play a necromancer my thralls would frequently disappear when going through a loading screen or fast traveling. Really annoying, especially if they have a bunch of expensive enchanted gear. Did any of the patches fix this?

I don't know, I rarely use Thralls. I did (and still do) have a Cultist thrall.

That is quite the contradiction. Now, isn't it?

How is that, he just said he rarely uses them not never uses them.

Unfortunately I dont think they did but I find it strange you're losing Thralls by just going through loading screens.

I rarely use the spell. I used it once on a cultist who is still my thrall. I see no contradictions.
