Going Bearback

Well, in the quest Going Bareback, I can't kill Frost Giants and Frostworgs, because I am exalted with them, through "Commendations for Sons of Hodir".

So, now I am exalted with Sons of Hodir, but can't complete the questchain, in order to have access to them.

Any suggestions for this to be solved?

I want to have access to sons of hodir.

Try setting them as "at war" under your reputation tab.
