I'm not sure if this bug has been discussed, I'm relatively new here, but I wanted to let you know all the same.

Last night I was tinkering with saving and loading race profiles and discovered (on my laptop at least) that I could create an Uber Race simply by loading other saved races over and over. The game didn't remove the old techs and abilities before it loaded new ones. The effect was cumulative, too. I could load the same race over and over and keep boosting my stats.

To "test" (abuse?) it, I created 6 races, each with different benefits and techs, and saved each one.

Then I loaded the 6 races, 10-20 times each, and ended up with something nasty. My planet size was increased 100%, my weapon strength 350%, my diplomacy was 200% ... and so on.

I figured the game would ignore the absurdly high bonuses once I actually started the game, but it didn't. My initial size 10 planet immediately became a size 20. My ships all had movement 23, my sensors were insane. After colonizing 10 worlds, opposition worlds started yielding to my cultural dominance... then I won with an Influence victory.

It was amusing, but lacked challenge, so I'm not going to bother doing it again ... my initial annoyance was that I couldn't load a race without having the previous race's stats overlapping mine.
