From: Montpellier, France
I'm not sure how this happened, but I have some theories... I'm a Quemano empire, and that planet was an independent human colony. I'm not sure, but I think I did try and fail to colonize the planet with a Keratov colony ship before sending a human colony ship and succeeding. It may be what made this bug happen. I don't think this is the kind of bug for which uploading a save will help, so I don't upload, but if you need one... Note that it is quite annoying that, when using the planer "build and send" button to colonize independent worlds, the AI choose a race unlikely to succeed. Well, I was lucky when I colonized the first of my human worlds with a Keratov colony ship, but I would have sent yet another race. This way, I lost several ships because I thought the IA would be able to handle this. With such a bug as the one in the title, I'm sure I did lost one or two extra trying to colonize with the bad ships from the good world...
