### Issue description

Can anyone help me debug why godot gives me these errors when i add a csgnode to a pre existing hierarchy?


### Steps to reproduce

1. Drop a csg combiner node on the node3d of your scene.
2. Drop a csgmesh using union and scale it up.
3. Drop another mesh using the subtraction setting, And push them into each other while making a house like this.
4. (Something I did that wasn't included) I used a triangle mesh.
