well besides the map having funky rivers (posted it on other thread).
I had a number of small bugs pop up when I was playing. here is the debug.err to the game(also the link)

I saw the following, during the coarse of one game:
1) Unlimited cities (for me, played the diplo-bonus faction)
2) an "invisible" unit

a guy i sent to explore, who soon disappeared (though his line of sight is still there). and i can not select him
3) a build option that should not be there

as you notice the white outline for the earth shard imporovement is the blueprint, but it has already been made in this city (same thing happened in multiple cities with diffrent power shards)
4) My unit got stuck in someone elses borders

if i got him to move anywhere the war decleration popped up
5) it's #3, but with farms
