Thank you!
By the way, I discovered another ... not quite bug, I guess, and just confirmed that it exists also in the original MOO. I got a message that all my transports were destroyed, but then still got an invasion screen ("X out of Y transports penetrated Sakkra defenses"). I think what's happening is that every stack of transports that arrives on a planet "runs the gauntlet" independently, and one stack was completely destroyed. It seems like that should make it easier for the defender, but I'm not sure.
