I had three bandits locked and attempted to fire multiple AIM-120Cs. On several launch attempts, the missiles appeared to fail to spawn or leave the rail, even though the launch sequence seemed to trigger. You can clearly hear the missiles detach and the boosters ignite, but no missile is visibly launched.
At the same time, the HUD shows an extremely high and unrealistic time-to-impact value. After several attempts, the missiles eventually launched normally again.
This looks like an intermittent issue where the weapon audio and launch logic trigger, but the missile does not actually spawn or render correctly. In case it matters, I was hosting the lobby.
