Yeah, that's a good point that you both have. It was originally done this way because of the way things worked in early alpha versions (where the host also set AI home planets, since the AI worked more like a human proxy then, rather than the way it works now). And it was also consistent with SupCom, I think. But anyway, the design has changed so much now that you're right, it doesn't make sense to have to clear the existing one first. I'll make the needed adjustment in an upcoming prerelease version. Thanks!
