Soul Renderer, Hearthflame, Soulkeeper, Thunderbrand, and Flamewind crash game on immediate pickup. May be others that crash game as well. I am using mythic metals and better combat, among others. Also, I will update this list with more weapons as I test them.

Please attach your crashlog

Most likely, you are running incompatible versions of Simply Swords and Spell Power Attributes. Please update both of these mods to the latest
