The system allows the selection of unlimited weapons so when say an AIM9 is fired it is then replenished on the aircraft. With the F-15E this appears to happen visually but doesn't then allow you to fire it. So if you begin with 4 AIM9 weapons you can only fire 4. Gun rounds and air to ground weapons are unaffected by this issue. Other modules at release 2.8.6.41363 are also unaffected.
