And now, even more, again from EAW.
I've figured out my planet assault problem, I went into one sector for it, and both "Planet assault" and "Planetary Assault" popped up under different names. Planetary Assault was the one I picked, sure enough that's the /good/ one, with the bases in orbit and all.
But when I start playing it under the new pack version, it bumped a Hydran hex I was attacking back up to 70 defense, from 30. It's done that on several other occasions as well. If its still using the campaign setup I had before, it shouldn't be using Planet Assault at all. Might have to start a whole new campaign again, and simply copy all the mission names from the readme into the campaign file. Ugh.
I also got Hydran ally while attacking a Hydran hex. Wonder if that's part of what happened. Wonder of wonders, without a Hydran on the team it worked right that time. Then I only get planet assault next round, with 3 ships. Must remember to find the truename difference between planetary assault and planet assault, to erase the 3 ship one.
And just when I had the KE conquered...
As for the homeplanet thing, I'm talking about in EAW, so I guess the OP fixes don't apply. Hope the OP patch fixes the "no starbases in late/advanced era" bug.
