Multiplayer game with multiple level

Hello everyone. I am developing a customized-monopoly game and I was wandering a way to insert "bonus level" while the main scene is running (almost Crash-Bandicot-like bonus xD). Precisely, I have my main scene and when player reaches a game cell, the scene relative to that cell has to be loaded. But I don't want the server to be destroyed and I want the informations got in the bonus scene to be updated by the server (for example, if I have to pay something in the bonus scene, in the main scene the total amount of money has to be updated). Could anyone help me to do this? Thanks in advance and sorry for my bad english >_<,Hello everyone, I'm trying to make a customized-monopoly game, and I am struggling with my idea. I am using unity LobbyManager to manage multiplayer online and I would like to know a manner to save the state of a scene, changing scene and then return to the first scene (the idea is similar to a "bonus level" while other level is running, almost crashBandicot-like xD). How could I do this mantaining the server and updating the informations got in the bonus scene?

Thanks everyone for the help, and sorry for the bad english >_<
