Hi, everyone! I got one profile of Skyrim which level on 48. Then I created new profile and reached to level 7. Well, I went back to my old profile level 48 and some part of levelling like Smithing (from 86 to 16), Light Armor (from 90 to 25), Block (from 75 to 50) and Sneak (from 100 to 26) but perks remain there. Perks remain there and unlock perks available like Sneak (Roll on the floor)... Summary :- Some XP for certain level went down after create a new profile... Help me please

Wow sounds interesting. Hmm well I don't exactly know but it sounds like a loading bug of some sort. Perhaps you should try the wiki or look it up some how.

Have you tried leaving the game totally, and then seeing if it fixed?

And what platform are you playing on?
