The issue is that the rotated labels for the gun types are no longer right side up after rotating a field. I’m rotating some of the airfields to maintain equal distance between the VH and the town at all fields which can otherwise vary by a mile.
When an airbase is rotated in the Terrain Editor, once built, the hanger view of gun positions in off-line play are correctly rotated along with the field, but not the gun type labels.
There are no issues with the runway spawns in the Tower or Hanger.
A quick search of the bug forum suggests this hasn’t been reported before.
