HDT PE - Consistent angular function, but regularly losing linear motion

[foreveraloneguy]

Hope the title is a decent description... This mainly affects NPCs, but see the problem on my PC as well sometimes. It seems that the angular parameters are consistently applied, but the larger linear limits and associated motions seem to start failing until an armor piece is equipped or unequipped - anything to get HDT to re-read the config and/or reapply the physics. Not sure... there's so little in the way of debug output by plugin it's difficult to tell.

 

Any tips on trying to sort this out?
