To anyone wanting to play around more with physics in the newer builds: I've found you can place your character(s), THEN the gallow, then activate the characters, then DELETE the gallow, and not only can you drag the characters around, but they will occasionally reanimate and active-ragdoll for a few moments before going limp again.
I've gotten this to work with the large gallow, and with as many characters as you can fit on them, all at once.
It's a neat bug and honestly makes me hope future builds will have a function to do this with a loose character, and this time be able to control animation strength and length, maybe even do it mid-walk and have the character almost stumble forward before falling down.
