Plot hole: Old Ash travels back in time to 1982 to snatch the Necronomicon before Young Ash ever finds it (which should, presumably, erase all of the evil events from the original Evil Dead film right up to the present). Upon escaping the cabin, Old Ash finds that the timeline has self-corrected, and his amputated right hand has reappeared on his arm. But he is still in the 1980s. If the timeline had truly self-corrected, then Old Ash's car, his friends, and he himself would have vanished instantly from the 1980s, because the purpose of their mission never existed.
