Buildings rotated 135 degrees counterclockwise when constructed in-game.

[Michael D. Hafer]

In Atlas buildings have their proper orientation (the "front" of the building should usually face towards the lower right hand side of the screen - there are some exceptions that face towards the lower left corner of the screen, but the point is, they should face at a 45 degree angle, like a diamond, from the default viewing angle), but when constructed in-game, structures face 135 degrees the wrong direction so that the "fronts" of the buildings now face the exact opposite direction from the camera.

This occurs with every Faction's buildings, no matter of they are PMD meshes or DAE Collada meshes.
