MediaTracker deletes itself

[ThaumicTom]

Sometimes the MediaTracker deletes everything you created in it. Open a map and create MediaTracker. Exit and try to edit again. The MediaTracker should be empty again. This happens very randomly, and maybe under weird circumstances (special map blocks placed, etc.).

I'm currently searching for a reproduction. This bug exists, and is very game breaking.

I use the mediatracker a lot and have not had that happen yet. But will certainly keep an eye out for it.

Is there a specific environment you are in when this happens (or regularly in)?
Is it Shootmania or Trackmania?
Are you having the problem with Mediatracker Intros, Ingame, End of Race or Podium?
Or is it when loading and editing saved replays?
