Why is every addon released so far underwhelming?

[GhostlyFrend]

It seems that your wish already has come true

Game has gone

Over night the game has simply disappeared from my PC. Windows Store now shows an install button. Is this the normal behavior for this crippled sim to just simply disappear? This is ridiculous. The game is shown in the apps but I cannot start it. Repair and Reset did did not help. Now I have to reinstall everything back. This is really ridiculous. P3D never did such things.
