I just wasted over 2 hours on testing with the giant at the farm outside of whiterun (C00GiantREF), his stamina is being forced to 0 for some reason by the game. This made me think I had a bug in my Smash of the Titians scripts.

I am not sure why his stamina is being suppressed but when I found this out I moved to the nearby giants camp and tested, and all was fine.
Those giants had normal stamina.

This was NOT the case before skyrim 1.6 as I had been testing for weeks with the whiterun (C00GiantREF).

So I thought I would post here and maybe save someone else some head ache.

I think this is the one the companions are fighting when you first pass that way.
I think they nerfed his stamina so the companions don't get launched into near-nirn orbit!
