I can't set a key for the staging sequence. It doesn't matter which button I use, the mod throws an NRE if I press it:
[EXC 01:26:23.781] NullReferenceException: Object reference not set to an instance of an object
Staging.ActivateNextStage ()
KSPAdvancedFlyByWire.FlightManager.EvaluateDiscreteAction (KSPAdvancedFlyByWire.ControllerConfiguration controller, DiscreteAction action, .FlightCtrlState state)
KSPAdvancedFlyByWire.AdvancedFlyByWire.ButtonPressedCallback (KSPAdvancedFlyByWire.IController controller, Int32 button, .FlightCtrlState state)
KSPAdvancedFlyByWire.IController.Update (.FlightCtrlState state)
KSPAdvancedFlyByWire.SDLController.Update (.FlightCtrlState state)
KSPAdvancedFlyByWire.FlightManager.OnFlyByWire (.FlightCtrlState state)
Vessel.FeedInputFeed ()
FlightInputHandler.FixedUpdate ()
Using Space for staging works though. Here's my config.xml: http://pastebin.com/cCMfRJxR
I'm using AFBW 1.7 beta (installed via CKAN) on KSP 1.1 x64 on Windows 10 with a HOTAS Warthog.
