Help me out with Unity Mirror

Job ID: 34856773

Budget: €8 – €30 EUR

I don't know why, but scene loading not works in my example project with Steam and Mirror.
I have 2 scenes, Main and Game. When I load the Game scene it writes error in the client who is connected to the host.
It writes "spawn scene object not found", but I added the networked scene object's prefabs to the NetworkManager.
