Levels and Directions for Out-of-Plane and Weak Storey Seismic Irregularities (Bug 2824)

Shearwalls sometimes reported the wrong building level or direction for which a Type 5 irregularity (Out-of-Plane) occurred. This irregularity could also be incorrectly allowed or disallowed due to the Weak Storey (Type 6) irregularity as it was using the wrong level or direction. These problems have been corrected.
