I have a game with a 3D board and game pieces. I have the board divided into tiles. When a player clicks on a piece and then a tile, the piece moves there. Right now, it's under construction, so the early primative pieces are floating around in space. All attempts to position the pieces in a starting set up, (this includes positioning by hand, and using the shift-s 'snap to'their feature,) result in the tiles and pieces losing properties. I cannot select a piece, nor can I select a tile. The rotation of the board still works though.
If it helps to visualize, I made a shot video of my progress for my friends: https://www.youtube.com/watch?v=hwFA1MlgZGY
