well that is true but all I was trying to do was add somethings to it, but from what I have read online there are things in tower 3D that you can change and things in it that you can't, and I told the friends of mine that maybe it is just better to wait and see what nyergesdesign does, as there are some errors in real traffic that need to be fixed, and I can't fix that issue in KLAS there is a error or something when I tell a certain flight of southwest that pushback has been approved and to expect runway 1L it is like it freezes at the gate when they are starting to push back and it will freeze for like 5 minutes then it finally does push back but not sure what would cause that in the airport KLAS
