I went through the code (on KSP 1.0.2°) and I found out that the developpers have made some changes. In the GameState.cs, at the end you find the logic for override the SAS manoeuvers. But VesselSAS has been moved in VesselAutopilot class. Replace with the foolowing code, this will compile and if you have update the path for your KSP folder. The .dll will be at the correct position. VesselAutopilot.VesselSAS VesselSAS = FlightGlobals.ActiveVessel.Autopilot.SAS; Boolean overrideSAS = (Math.Abs(CurrentState.pitch) > VesselSAS.controlDetectionThreshold) || (Math.Abs(CurrentState.yaw) > VesselSAS.controlDetectionThreshold) || (Math.Abs(CurrentState.roll) > VesselSAS.controlDetectionThreshold); VesselSAS.ManualOverride(overrideSAS); Note that I just execute the code, I'm about to config this then give it a try.
