I have a 'npc_template_maker' that is using a combine soldier as a template. I want it to spawn an unlimited number of them but only allow one to live at a time before spawning the next one. I can't get it to work. A trigger_once is targeting the 'npc_template_maker' via 'toggle' input. The 'npc_template_maker' properties are as follows:
Name: wave_level1
Start Disabled?: No
Num, of NPCs: 3000
Max live NPCs: 1
Name of template NPC: combine_template02
