Rigid body transform not synced on parent object change

Also they are always spawned at 0,0,0 regardless what I plug in the "Spawn Scene" node.

Start by opening the attached sceneroot.zip and reproducing the issue through the Spawn Scene node, checking both the spawned position and rigid-body behavior after a parent object changes. Done means the spawned scene uses the position supplied to the node and its rigid-body transform remains synchronized with the parent.
