[RANDOMINATION]

Ok so i've loaded in the latest TF2 items plugin, the snapshot it seems. I've read in many different places that this code...

"custom_weapons_v3"
{
	"*"
	{
		"*"
		{
			"1" "254; 4"
                        "preserve-attributes" "1"
			
		}
	}
}

...should disable airblast griefing on opposing teams, but I can't seem to get this to work. I would like the pyro to be able to airblast projectiles, but not players. Is there something I'm doing wrong here? The plug-in is listed under "meta list", so it did load in and is working.
