I don't know, I just heard another on channel complain about the same thing. The difference being, he was in a SBD (not sure if he was able to score as attack or bomber ... if it matters anyhow). He struck damage to a fleet and then landed without any damage reported. I asked if he received any perks and he did receive 2 perks.
I can also, recollect instances of being surprised that no damage name in lights hit the text buffer. So, there might be something other than reconnect in play.
