Various things I've noticed over the last week or so of playing the beta -
Every so often when I try to open the domestic advisor the game crashes. I think it might be related to having captured a city on the same turn but I didn't keep the save game. (attached crash report)
Rams receive the free City Raider promotion when playing as a Tactical leader, but not when a non-Tactical leader builds it in a city with a great temple and Hedonism. It should be both or neither, no?
Colosseum-built Blowgunners seems to work as intended but the combat messages are very strange. (attached screenshots)
Every once in a while when switching civics for 1 turn of anarchy, the anarchy doesn't actually happen -- my brother thought it had to do with Theocracy but it only happened twice that I remember.
Start locations seem to be wonky on at least the Earth (Standard) map, I set up a game with Mali, Kongo and Turkey in it and they started in seemingly random places (tho the other civs - England, Mississippi, Brazil and Korea were all correct)
You mentioned lowering dissent for the AI in this version? I think it may be a bit too low, now - playing on Noble difficulty the AIs seem to almost never have rebellions, let alone new civs spawning (though I haven't played past the Renaissance often)
