Similar to the previous issue where your arms were frozen on paperdoll, Your main hand will freeze if you have an item in your offhand but it unfreezes only if you go in third person. Otherwise, going back to first person, it freezes.

That was fixed in the latest release. Please check your version(and remember to update TRansliteration lib at the same time, else it won't work).

I am on the latest version for Not Enough Animations 1.3.3 and on the latest for TRansliteration lib and I still have the same issue. It doesn't freeze the paper doll yes but when I have an item held in my offhand, then it does freeze. If you'd like, I can show you proof that it does this.

This had been resolved for some time.
