Yesterday my Viggen was hit while on the ground. So I repaired, which completed, but when I tried to re-arm with a Modern Anti Ship, they kept appearing then falling off the plane. I'm relatively new to multiplayer DCS, so I couldn't say that it might perhaps have been a problem with the airfield I landed at, but I would've thought that if the airfield didn't have any weapons available, they wouldn't even appear let along appear then fall off the plane.
