This island works in conjunction with the Promethium harvesting platform, placing biter eggs into silo only when the platform is detected in orbit using circuit signals. Otherwise eggs are used to make Prod 3 modules and electricity using heating towers. PLEASE NOTE: It can also automate Biolabs and Captive Spawners. But the Captive Spawner cryo plant has a power switch that is TURNED OFF by default. Only turn it on when you need new Captive Spawners. Otherwise, spawners kept in chests SPOIL!
