Playing the Korx if that matters. New Beta 4.
1) I've noticed that in the diplomacy screen when you click on money it doesn't always pull up a green amount that the AI will accept. About 50-50 so far. A bit annoying but not a game breaker.
2) And this is a biggy. In the diplomacy the indications that a tech is unique tech (the *) is gone and the racial logo when looking at a unique tech by right clicking is also gone. I've also found that races are trading around unique techs that I don't believe were tradable before. Arceans had Slave Pits (not sure if that was tradable before) but more weird is a minor had Weather Control (which I'm pretty positive isn't tradable). So it looks like some old tech code got merged into beta 4 perhaps.
On to play some more, will report any more things as I come across them.
