Map loading problem

I think that unreal has many weird bugs. In my game project there are 6 maps which is downloaded good in standalone and packaged game. Now I added 7:th map and tested it. Map is downloaded okay in standalone mode, but when packaged it download back to main menu. And blueprint is okay and same as in other buttons in main menu. What is problem and why only packaged version. I use 4.11 in my project and epic should fix this kind of things
