#32: "{actor} hits the Android" Enqueued by CrewHitsAndroid (40941). The "Android" is the long-game AlienTargetID slot (33703) — the dormant traitor crew member that UpdateAlien (40826) activates on first encounter with the alien. The actor placeholder is filled from CrewIndex (33700) = the slot currently being dispatched in combat state 4. Because the (IX+1) sprite-class match in CrewAction4_Handler is by class (not unique slot ID), the message can fire for any crew sharing the Android's class — see CrewAction4_Handler header for the ambiguity.
