Here’s a weird one,
I am flying the Mooney, Flight plan below;
I am on the 67N40-66N40 leg, but the leg is not shown on the map, my plane flies towards it anyway; (I realize this screenshot shows me on vloc, but I switched to GPS and it still went to waypoint 66N40 as per the flight plan, instead of 65N39 as shown on the map.)
when I get to the waypoint a new leg is created between 66N40 and 65N39, this (new?) leg existed in the flight plan to begin with but wasn’t on the map
