Resetting a map for matches.

I have a way myself, but you know, life is all about trying new stuff. Is literally scheduling a Asynchronous task to copy a folder better then just a single line of code to setAutoSave to false, then unlod+load level?

Are there any differences?

I personally use that one:

(Last post).

I use it because it doesnt require a task and also seems to be very simple.

I have something like that, but improved with an Async task. I am asking of the setAutoSave way

I think it doesnt work, as I tested that by myself the levels were only reset when I restarted the server, I also did loadLevel()
