I’ve just noticed that the GPS info on the HUD keeps turning off. I right click on the HUD, turn on GPS in the HUD items menu and it works. But next time I start MP it’s gone. All my other settings seem to stay unaffected as normal.
Seems to be a bug in the HudItems plugin.
Delete your config.xml from Documents/Mission Planner, or edit it and delete the line <HudItems>GPS</HudItems>
