I'm noticing strange forces on the ties that don't look like they should be there.
This bot seems to spin, even though it's just designed to tie itself into a circle. It's attached.
The spinning seems a little odd. Where's it getting the energy from?

Anyone else noticed this?

It's an inbalance in the physics, a result of the calculations for tie Hooke, torque and collision bot forces.  I'll take a look and see if I can tune it better.

This kind of thing has given us all headaches for years.
Tie physics are horrible.

And Eric is like an aspirin, makes DB barable for us users.

Yea, that Eric guy walks on water and heals the dead.  I'd lift weights, but that is like putting more sand on the beach...  

Hey, check out 2.42.9d and tell me if you like how ties work now.
