09.25.2023 Special hitches and quad fix update

Added and working are four new, dynamic poses intended for use with Phys Bones! If you add Phys Bone scripts to your pose clone (and manually ignore all the "offset" transforms affected by each script, since their auto thing is like. confused) you can now take advantage of three different "hitch" types for hitching your hind body to your hips--XYZ, good for floaty-type poses, YZ (the same as the default hitch!), good for rolling-on-your-back poses, and Y, good for sitting or lying down poses. The onboard Sit toggles gravity on your hind.chest.001 Phys Bone and is handled specially in a few other ways, but you can freely replace the others with your own poses. i think. 

Also fixed a bug with quad avatars affecting the base of their necks. Sort of. The script is being posted as-is but you'll need to reset a position constraint yourself. See this video:
