So, after reading a bunch more on the forums, I rread that we haven't required a Havok Object in 4 years?! Mods like HDt All-In-One have "hdt havok object.esp" which to my understanding relegates the HDT for NPC's. It is a playable item in All-In-One and is not a hidden or unplayable. Is this still required? I now use Realistic HDT XML as the aLl-In-One XML's are out of date. (They lack the 255 HKparam fix)
