Hi, I also just ran into both of these issues. First, I encountered the 100% reproducible CTD by using multiple bindings for decreasing the various prop pitches. Then to solve that issue I only assigned DECREASE PROPELLER PITCH and encountered the step-by-step prop desync. It’s so weird and doesn’t really happen every time you press the button. Very annoying, especially now that we have some really nice multi-prop planes in the sim. A fix would be very much appreciated!
