Dort gibt es einen Trick.
From Jeff Mayse over in the DCS FB Group ...
"Temporary fix for hornet load out. Load 2 of each type A2G weapons you may want to take on a subsequent trip, ie. 2 83, 82, Zuni, 2.75, and 99. Do this before you turn on battery. Then start airplane normally. After start load whatever combination of the previous weapons, ie. all 82, Zuni and 83, whatever. They will work and you can load any combination of those 5 every time you reload.
This must be done every re-slot.
