Thanks but my root node is set up for collisions so that’s not it. It seems to be something related to attaching and detaching. I had a similar problem when I did ragdoll on my character. Once you enable physics, something weird happens (I think when it detaches) and the mesh and/or capsule collision setup is affected. Like when I tried to get the mesh out of physics and back into the capsule, it kept colliding with the capsule and jiggling all over the place. Only when I manually (in the editor) changed any collision setting did the correct settings come back. In the end, I had to check on tick if the collision channel wasn’t ignored, and if so, turned it back to ignore. Anyway, I think something goes wrong when you do attach or detach.
