No comunity addon

Brief description : Deleting the last waypoint of an accomplished flight plan crashed the game. Sometimes cant delete a waypoint from the f.plan. Plane : TBM 930

Detail steps to reproduce the issue encountered: Delete starting point , than the destination. after that try to remove the waypoints. Maybe it just me but is there a menu or something to delete the entire FP at once?
