last game saves may as well be considered corrupt they load but if try do anything such as combat or tlk to NPC will cause whole console to crash but newer saves are uneffected
is bit annoyed by it because new levels can barely do anything and then it cost soo much to get enchanting up
I've had this problem a few times with TES games, when I have to start a new character after playing a high level one it is tricky to get back into it.
