If you take a "kill a cyclops/basi/medusa/hydra" mission and dont go to the mission signal source, instead go to say an AXCZ it doesnt count.I believe this is correct.
Stacking lots from Aegis ships.
None from Rescue ships. I was doing this and checking over several days.
Only got this to work with Scouts, not Interceptor missions.
If it just says "kill an interceptor" it does count in an AXCZ.
Or at least it did 3-4days ago
