Hi, thank you for making this mod, without this I wouldn't be able to play it with my new joystick, but: I have a similar issue here, the config preset (advanced_flybywire_config_v21.xml) is overwritten with default file. I tried a bit and it seems to happen when: - Starting a new game (even with the same save) and opening the config panel, or - When reverting a flight and open the config panel after then. No issues when using the config panel in the same 'session'. My setup is kinda complicated, I'm using a Saitek X55 HOTAS through VJoy and UJR (Universal Joystick Remapper) because usage of the X55 drivers is very laggy and KSP becomes unplayable (It seems there is no solution available, only the Workaround with vJoy and UJR). When the preset is there, everything works fine. I'm really in need of using AFBW, when the controls are defined in der KSP Menu, it chooses randomly what device to use (X55 or Vjoy). I noticed further, that some devices disappear in the config panel and appear again a few moments later, is this a problem?
