In Edit > Project Settings > Maps & Modes I set ServerDefaultMap to Map_FleetBrawl_0.
To test, from the editor, I started a Stand Alone Game running a dedicated server, with 2 players.
I unchecked Auto Connect To Server because I wanted to test manually connecting to it.
Both the players correctly loaded the MainMenuMap, but the server also loaded the MainMenuMap. It appears that the ServerDefaultMap in project settings does not dictate what map the Dedicated Server loads on startup?
How do I tell the Server to load a default map that is different from the default map that is normally loaded?
