I had the same issue when I tried to move a waypoint with TDC. I think the TDC moves in relation to North, East, South, West, rather than up, right, down, left.
Hello - I was doing some multiplayer Fox 1 practice in the Mirage and I seemed to encounter a bug. I was flying in the Mirage against a friend who was in the F-15C. In a couple of our fights, we would Fox on each other at around the same time but my missile would hit first (the 530D has a lot of energy). I assume this meant that the missile he fired would lose track, but it would still hit me. It seems like the track file is still generating, but I have a Tacview file which seems to point to the conclusion that the MH is still able to track after its host is killed. I will attach it to this post. One example of this should be at about 04:54:34. It is between Aero (me) and Kester. Ignore the other F-16.
