My computer is plenty capable of running Oblivion. I narrowed a couple problems down to Bravil Sea Domes, and the enemies do seem to attack me sometimes. Mods: Dark UI, Themed Loading Screens, Clocks of Cyrodiil, Adrenaline Oblivion, Deadly Reflex 5, Illumination Within, PJ's Lightning, Symphony of Violence, AlexScorpion's Sneaking Gear, Thieves Arsenal, Ivory Sky Base, Natural Environments, Altair's Gear, Lost Alteration Spells, and a personal house mod I don't plan on giving out. My personal mod has only a couple problems, and none of them have to do with enemies not attacking. I think. :P Edit: Okay. I went through and disabled every last mod. I went to my testing place, the Sanguine Shrine, and attacked the Kajiit lady. She wouldn't attack me, and did the same thing that the highwayman did.
