I was working on making a quad-tracked vehicle with Clockwork + VS2 + Trackworks when I found this really weird bug. Basically, the setup was that I had four tracks connected to a basic chassis via phys bearings, each loaded with some netherite blocks so the tracks would have suspension force on them. But for some reason, I found that if I did not put at least one row of blocks in the red areas marked on the screenshot, the tracks would inexplicably spazz out and the whole vehicle would go jittering about in the sky. Adding some, but less than a full row of blocks would stabilize it and lessen the spasms, but not completely eliminate them.
I can't quite offer exact steps to reproduce beyond just remaking whats in the screenshot, it took me almost two hours just to figure out what was going on and I still don't understand why it's working this way.
