I finished a bombing sortie on a single player mission then landed at Al Dahfra AB to refuel/rearm. When I tried to do so, I got "not available" for every single store for the aircraft and no response from the ground crew. In attempting to research this before I posted, I saw there was a similar bug with the F-16 as I linked below. Al Dahfra AB is set to Blue and unlimited liquids and stores in the mission. I've added screen captures and the .miz file to this post.
I have been able to rearm/refuel on this mission before.
I did some more playing around with this mission. This occurs at Al Dahfra at night, when the plane is in an area that under lighting such as a lighted hangar or tarmac. When you taxi to an unlighted area, you are able to rearm/refuel as normal.
I don't have a .trk for this mission because it was an hour in before I discovered this or what the bug might have been.
I originally posted with screen captures of the mission, the mission settings, and the .miz file itself under the main F/A-18c thread before considering this might be a bug. No one responded.
