Adding rotation to a bsp breaks extrusions

Adding Rotation to a bsp breaks future extrusions, causing them to incorrectly render.

1. Open Editor (any project)
2. Go to Modes>Placement>BSP>Cube and add a cube to level
3. Select cube>details pane>transform>Rotation (90,90,90)
4. Open Geometry Edit mode
5. Select cube, select a face
6. In edit mode, set to extrude
7. Use transform tool to extrude side along axis that the face is rendered on (if face is facing X axis, extrude down the X axis, etc.)

Results:

Several of the faces on extrusion will not render.

Expected:

Extruded faces appear as solid faces on the bsp.
