Muliplayer compatibility

It means your map is not up to "par" with the multiplayer map restrictions enforced on servers in 1.1.0.1 or better, basically, make your huge wide open areas less huge and wide open. Make sure pickups are at a sane distance away from each other (e.g. don't spam 5 healh packs and 5 kevlars all within the same little area), and last but certainly not least, read the docs!
