In Polynesia game (without mods):
Maori warrior promotion: embarkation with ocean movement: can enter water tiles, can enter ocean and +1 sight when embarked.
What happens: warrior embarks, gets the unique polynesian boats and is out of moves. Can move 2 tiles on another turn.
Phoenicians: I set up a new game with all your civs except Carthage, without mods (only info addict) and the crash didn't occur. I built two ships and a harbour, everything works as it should.
Game with mods (Thal's Balance, City states leaders, R.E.D Modpack, Info Addict): worked properly this time! There were proper promotions for the ship and the harbour worked as well. I think the first time was just a random crash, although I was surprised - Civ5 crashed for me only 3 times in 3.5 months.
Minor comments: The Phoenicians are great! An early naval gold-oriented civ was much needed. All of your civs are pretty unique, looking forward to Dacians and Scythians! And you did a great job with the leader screenshots. Those painted mini figures fit really well.
There three things that bug me though.
1. Is it possible to assign region-specific music to the civs? Now it's a little sad to hear the meny theme over and over again, unless I meet a vanilla civ or play something in winamp. ; )
2. The main colour of the Britons is quite bright and, IMO, candy-like. If it's their historical colour then OK, but I think it would look better a little bit faded and darker, though.
3. The Gaulish and British maps in civ selection screen and DoM also have those bright colours and that doesn't look good. OR maybe they're some placeholder for now?
But, those are only minor issues, don't mind me ranting about them
