Don't know if I'm able to join tonight I'm afraid, have some stuff to do. Anyway, hosting 3 matches and 18 holes on each takes quite some time finish. Therefore, I was wondering if it's possible to get this achivement a quicker way.
Edit: It just popped up, at the begginning of my third hosted match. So I guess the system tracks those matches that didn't finish. Nice that it popped up at the beginning, in stead of at the end of the match
