Snowball Event

As some may already know, I've found the Snowball Map (ID: 109060000) which didn't seem to work for some reason.
After much speculations, we decided that the codes were missing for some reason and after some searching around (google) it seems I've hit the jackpot.

Could any of the GMs code that in for us it's a fun team based game, it'd be great if we could get it to work since not many other servers have this kind of game
