The reason I want to be able to do it myself is because I don't like the new testers as opposed to the very first one that had a single command that reset a very tiny map. No menus and fancy stuff.
If I know the way to do this I can embed the command in whatever map I want and in particular, the new maps that come out every season. It would be much faster instead of waiting for others to release official testers with a bunch of useless (for me) additional menus and choices that take time to go through before you start playing the game.
What I'm asking might be very simple, but I've already tried to do it on my own in the Editor but it seems too complex.
