HI all, I first have to say thanks to all the hard workers on every mods! It is awesome. But now I have yet to face a big new enemy called Dwarven spider. Because it causes my skyrim to ctd after I encounter one... Everytime I encounter one my skyrim crashes. Does anybody know how this happens, and how I can actually fix this? I thank you all for you effort for even reading this. Thanks in advance! Greetz, Tai
