When a destructible is a parent and has physics enabled the child will not follow and instead stay static.
When the parent is a normal moveable static mesh it works correctly also with Destructibles as the childs.
Apparently it also breaks the collision of the childs when the physics get activated. I could not trace the collision of the child anymore.
This has already been reported with UE-6826. This is currently backlogged with no time frame for when it will be addressed.
Thank you!
