For Killing Machine Medal, the tip from EliteSlayerX is not a bug whatsoever. As a level designer for counter-strike and half-life, the reason for zombies spawning after passing the doors is mainly because of a trigger. "Trigger_once". Once touched, the trigger target will be triggered immediately, no delays (unless the designer delays it). This is not a bug.
