Well, I just got Oblivion loaded and my friend came to visit and loaded a ton of mods to my PC, better cities, natural envirnoment, crowded roads, stealth overhaul, more weapons and armor, there are now strawberry pies in my game, archeology guild and much much more. But wtf, all my spells cost 1 magicka to cast and he has no idea what mod is causing this.. I'll put up all the mods I have active right now into a huge list right now, but if anyone has past knowledge of why this happens, feel free to let me know right away. Theories of possible fixes of this are also much appreciated.
I had the LAME (version 1.0) active when I first saw it, deactivated it and all spells still cost 1 MP.
Help a noob, please
