I took the liberty of editing this slightly to add filtering capability. This works for me 100% of the time on a Windows server.

Having some trouble.... I USED to have this plugin active but no longer have it running... yet there are still no AI infected spawning during games.

Is there another cvar that can do this? I've gone through server.cfg and plugins numerous times now.

EDIT: I found the setting in the zcs plugin.

Anybody can make when tank spawn, can change type infected spawn ?
