I have a zone_2, and when i go to it from start_zone, the zombies that spawned in start_zone stay there. and any zombies that are yet to spawn, spawn in zone_2. And my start_zone is inaccesable from zone_2, so the zombies stay there untouched. 

function usermap_test_zone_init()
{
	zm_zonemgr::add_adjacent_zone("start_zone","zone_2","enter_zone_2");
	level flag::init( "always_on" );
	level flag::set( "always_on" );
}
