My game also crashed when loading Magolor.

I haven't had the crashing problem but I do think the character takes WAY too long to load. Stalls when trying to load certain scripts. I don't know why that necessarily might be.

I had a similar problem with VWizard's Magicka Wizard mod but that also had the side effect of the fact that my computer just couldn't run the character without massive slowdown on the character. Magolor also has frame rate issues which cause a lower frame rate though its nowhere near as bad as Magicka Wizard
