^ is that RPT from a test after disabling the HC?
1623 ALIVE AI Distributor starting.
1624 ALiVE AI Distributor detected no HCs, idling for 60 seconds.
Also you have far too many objectives in the mission which will cause issues:
1590 ALiVE OPCOM created 598 new objectives!
1598 ALiVE OPCOM created 1261 new objectives!
Please lower the objective count for performance reasons, suggested is below 80!.
RPT shows only 5 transport units spawned by ALiVE.. I am unaware of any limitation on this number... and you say it's not a specific chopper that won't spawn it seems random?
