Using the Kestrel, sometimes my weapon recharge bars get cut in half, as if my weapons officer suddenly gained multiple experience levels, even though they didn't. In the latest instance, this happened after a fight, not during it. I had just saved a Federation ship from the rebels, and they gave me a Breach missile and some scrap. Once I accepted the gift, my weapon recharge bars got cut in half, and I think I heard the "level up" noise. This isn't the first time something like this has happened.
Why did this happen?
