While playing Beta 6.1 I found another bug - due to previous attempts playing the same custom race I have a bunch of old ship designs and I found that if you have two designs with same name - the game does some kind of parse based on the text of the ship name not the actual design you choose for your production qu. So if you making a ship that requires special resources it shows the resources for both of the ship designs as being used up even though the ship you making may only use one of the two resources that both designs utilize.
I also noted that the timeline section of the GOVERN Tab did not show all the races in the game just what looked like the first 5 although I diplomacy screen seemed to know all the races that you had discovered and ranked either of them in the various categories unlike the Timeline screen which seemed to be limited to only like 5 races for some reason.
