Parts getting stuck/unclickable

Everything I pull out of the parts list teleports to the place where you see a pile of parts. I can't move them from there, or even select them. They are where the game thinks CoL should be. Another problem is center of lift not being calculated. There are wings, but CoM is shown as being below the plane. When I hide CoL, I can select parts previously piled up, but not rotate the camera or move those parts.
