I know. I think that those races were trying to use the Research files from the normal data set. I have no clue why they would do that, when the other races just used the default B5 ones.
There are not enough races for a high player number game. The game I am running has a couple duplicate empires.
Maybe you should put in a warning about that, or mod the settings so that high player starts can't have more races than there are in the mod.
Several of the races didn't get empire names in the game. It's very odd.
