MacOS 10.13.4, KSP 1.4.3.2152, Saitek x56 Rhino stick and throttle
When I assign axes to their corresponding controls, KSP recognises the movement and all looks well:
But as soon as I hit "accept" and reopen the assignment window, it's gone:
This only applies to axis movement, as buttons, switches and triggers work just fine.
Tried a full reinstall of KSP, and the joystick(s) are fully recognised by MacOS, but alas, the outcome is quite the same.
For the record: I also tried manually editing the settings file (and undid that as it did not work), and the plane is not responding to any axis movement (but buttons work just fine.)
