Im having no luck with finding these, I know they are at different offsets depending on the save, IE how far and level played to, invi and all that. Does not help that im not the best at hexing either.
Edit: Okay, I officially got my level back down by hexing it. I took my save before I changed the level and made a copy, then changed the level. I then proceeded to look at both with HxD and compared which values changed IE-level thats how I found my values. It seemed weird but I believe I found two level values by the XP values. The First one by the name everyone mentions is just what it displays when you highlight your save. They both can be diff, first one should not effect your chars actual level from what I ran into IE- trial and error.
