With the latest PTS, Atmospheric brakes are now being obstructed. As far as I am aware, this was not a change we were warned about, and on the PTS has broken 90%+ of my, and my friends ships.
If this is intended, this release is NOT the time to make this change. We as players need time to update constructs to work properly under the new requirements, and we cannot worry about making said changes, while we are also trying to test the new elements and systems on the PTS.
