I can safely say it again Force Hosting is now Fully Confirmed! XP Lobby as well!
For now, to make a XP Lobby, a local file must be modified to make it work. Config_mp.cfg the other part, to force host, will be from the tool.
Unfortunately, making a XP lobby will pretty much give all killstreaks to the player on the first kill since it works with a point system. But hey.......... Its working.
