Good to know. I recall seeing this during S4 but after a few seconds SNB would come back up. There was claims of double nukes at the time, if I recall correctly. But I was never able to fire it off twice. I don't play sci a lot, so I may be out of date on some things with them. I don't recall this exact event in the past and can swear I've seen it a lot more recently. Ergo this post.
More then likely it's related to the old Torpedo Arc/Power arc bug, where if you were in arc, but activated the power as you lost arc, it would fire but not fire and put the power on cool down?
It seems so. Also, just remembered, the bortie auto cannon does the same thing. Target moves, the "warm" time of auto cannon almost finished and it's about to fire, then target goes away, auto cannon didn't fire, cool down begins. Lucky that's not an important pvp weapon due to the crappy accuracy. But it seems to be a problem between client and server, I think client sees the target in arch, fires, sends the server the message than it fired so server sends back to client the "put subnuc on cool down"(or simply the client puts it on cool down), then target moves away, subnuc "misses" (due to the time it "travels"from ship to ship), client has the subnuc in cool down.
