1.0.6.0 Pure human colony produced a keratov colony ship

[Florestan]

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...

I would be inclined to question the purity of the colony.  The most prominent race will be used for the icon, but other races can be present (I am currently eying a planet settled using Ikkuro, with a mixed Ikkuro/Zenox populace). In other games I've had 3+ species on a single planet.

Look at the planet from the Colonies screen, and have peek at the population detail for it. //Torrenal

This shouldn't actually matter: Even an impure colony still produces colony ships of the dominant race, unless this was changed.

I think that this will not always the case. For example you have a multiracial colony, then you go to the Colony and Expansion Planner and you choose eventually a volcan planet to colonize which you will normally not able to colonize but you have a related alien race in one of your colony present then the system automatically choose the dependant race and therefore the colony. So you have now a colony ship with the proper race. But I think that sometimes there could be a failure so that the system choose accidently the wrong race on that special colony. Sometimes you can conquer a volcanic planet colony with different races on it.The predominantly race was perhaps conquered by an other empire and you have it conquered too, so very later in the game you got some migrants from any other races of your empire to that colony especially it owns a ruin as I think.
But I could be wrong after all...
