Ah ok I see I did misread it. Apparently there’s a lot of issues here and it sounds like they might be unrelated. The first thing I would try to test, is removing the unsung ORBAT units from all of the modules, and seeing if they adhere to the blacklist rules using BLU_F and OPF_F instead.
The wrong units spawning might be an issue with the ORBAT creation itself, so you may want to post the files for review here.
The virtual AI spawning directly beneath insertion helo’s could be due to spawn settings (for example, if you drastically lower the Virtual AI amount from the default 144 to something like,25, that can cause odd spawning problems) or server strain, but tough to say just based on the description.
This is why I feel like it might be best to try and isolate these one by one by removing the unsung ORBAT factions and using vanilla just to see if the behavior changes.
