RC2: Tile layer rotated in right pane.

Seems like tilemaps are working for me now in RC2. When I drag a layer into the game pane, save and press play, the layer seems to be visible now.

So I go into the tilemap editor, make a simple layer, save it, close the editor. When I get back to the level builder my tilemap is in the Layers rollout, but it's rotated 90 degrees. It appears oriented fine when I use it in the level builder, though.
