Issue description

I am generating a number of CSGMesh3D objects and putting them in a CSGCombiner3D. All meshes are set to be a union. Sometimes, this generates random holes:

And, potentially related, when moving the mesh with the hole on the Z axis, the engine freezes.

Steps to reproduce

1. Open csg_bug.tscn in the editor
2. Look at the red CSG mesh
3. Optionally, try to move the red CSG mesh on the Z axis
