Need an enemy

[Annex]

When firing two or more weapons at the same time at the same target, when the first weapon kills the target, the other weapons(s) which are still in the process of firing but now no longer have a target results in a "Need an enemy" text appearing in the center of the screen. This text will be there, even with multiple ships within firing range. I can easily repeat this bug and have this text remain centred on the screen almost indefinitely during a fight.
