"X" and "Z" coordinates are mirrored; "f" position is rotated 90° clockwise.

Previously, the issue was concerned about the Sunrise/Sunset cycle being from North/South respectively, instead of East/West (that may still be the case if the coordinate system is indeed correct).

However, the real issue may be that the "X" and "Z" coordinates may be flipped/warped; the "Z" (supposedly "X") coordinates (positive/negative-wise) are also mirrored.

The "f" position may also be affected as well (completely rotated 90° clockwise).
