Child Actor Component Collisions are invalid and doesn't collides

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.
