Spring RTS Engine

I've just spent hours trying to get a couple new players able to play BA. Total failure.

It seems to be a SpringLobby config/preferences issue but I'm not entirely sure, and exactly why it's messing up such??

Its not a secret that springlobby is a pain to use
example : most players don't even know that they need to manually clean the replay folder very often, or the lobby will be very slow
