i have 274 mods, with the unofficial patch, for both oblivion and shivering isles, as well as all the normal dlc...21 of them are turned off, either because they cause issues, they're extra esp.s for other versions, or they are unable to be turned on without causing crashes...amoung the ones that cannot be turned on because they cause crashes are estrus, anequina manor, tales from elsweyr, barrow field farm, extravagant masks, side's backpacks, jq&dm scripted backpack, better benirus manor, and sides sailing ships.
