The linked posts are of the Garmin system yes but not the same issue and except the first they have little relevance. My avionics or the MFD do not freeze, the whole game does. Neither does it seem to trigger from knob usage or dependent on time in game. The bug seems directly related to the flight plan screen or waypoint display in the Garmin systems which IS vaguely mentioned in another post, however it’s a post that lists about a dozen other issues with no screenshots or specifics. garmin issues
I made this post to keep it clean and on a single topic: Navigating the Garmin MFDs crashes the game and seems related to the flight plan and waypoints menus.
