Thanks for your reply. I just created a new GameState, assigned it on world and from settings but it is still the same.
What do you mean by `need to copy all that you’ve done into the new gamestate you just created’ ?
There is any existing gamestate file in the content menu, so I do not know if I changed it before.
I also tried to use engine’s existed GameState, but once I changed this from GameStateBase to GameState, menus for the game does not play once I click to play.
