I've been having this problem all day. What happens is that when I click a joint once(I'm sure it's only one click), the joint movement changes twice in quick succession. i.e. I click on my knee once to contract, and after showing "contacting knee" for less than half a second, it goes to showing "holding knee". I'm having this problem in freeplay and multiplayer, and I'm using the Toribash 4.2 beta 3. I'm pretty sure this problem just popped up today. Is this a known bug, and is there a fix for it?
