Hey that was weird. I re-uploaded them for you.
So to clarify with your set up:
You have the separate objects all with collisions turned on, and then a combined version with collisions turned off that you attach to?
Some ideas as to what could be causing your issues:
Your sliding attachment is too strong. How stiff is it? Cloth is by default 'weaker' than tissue. I would start with a sliding attachment value of 1 x 104 (or even lower if you're mainly relying on collisions to do the work)
Your sliding attachment is attaching to a surface that is moving around a lot underneath. You can use paint by proximity to help you with this. Use it to ensure that only the adjacent surfaces are participating in the sliding attachment.
Your contact stiffness is too high. Change this to ~1 x 106 (zBones and zCloth) . High values introduce noise into the solve and can cause instability.
Last but probably most significant, some of your underlying objects have self intersections. This will cause your sim to rip apart. You can use our self-intersection tool to determine if an object has self-intersections. If self-intersections exist at any point during the simulation, then we can't guarantee that collisions will behave correctly.
Definitely double check that collisions are turned off on your combined bone object.
Let me know if any of this helps your results
