I have noticed that only 1 of the 4 bombers spawn in my test campaign - does anyone know what might cause this? Doesn't matter if it's a ground or air start. Yes I have double checked the. mis and 4 planes are present. - Fixed! corrupt .mis file. too much manual editing. 

I am learning so much! I am using this forum as notes to myself and others. This was also caused by a weapon loadout issue. I had the correct loadout in the allpayload.dcg (so no pink plane). However, I had the wrong loadout in payload.dcg so (...not the .mis file as I said before).
