I don't get Error12's anymore since I started playing heavily Modded though I used to get that a lot and it was worse if the EA bugfest was turned on as it tends to run way too many events all at once and my game's story progression isn't using nearly as much memory as the bugfest used to.I also use awesomemod to disable that broken automated school assingment system which used to cause saves to become unplayable and made larger worlds mostly unplayable.I also have onmy 114 Nraas Mod files and about 700 other Mod files on top of that.
