If you have a Mod with new Keybinds and let the user set them in the Options menu and save them, you are fine until you unload the mod, start DayZ without it and then start DayZ again with the Mod loaded again. Your keybinds get reset which is very annoying if you play on multiple servers and one server does not use the mod with the custom keybinds.
Since all keybinds should have unique names, why don't you keep them saved in the config even if the corresponding mod is not loaded ? Would be great wo have this one fixed
