I get this a lot too. My success rate of getting the weapons off is only about 50%. When I mix weapons (eg:CBU’s + LGB or 2) whatever I select first mostly works (CBU in CCIP near 100%), the second weapon group almost never. And that’s in any release mode. Procedure is right and I can watch the display such as “2 GBU-12” briefly flash “REL GBU-12” then back to “2 GBU-12”. But they never release. I just do the SJ then act as an airborne FAC, locking up targets in the pod and getting the AI to attack my target, they never seem to have the problem. If anyone has any hints, please I’m all ears. Frustrating as heck.
Note, this is only with bombs, all powered stores work as advertised.
