Arabia flips the clam tile 1S of Athens (as well as 3 tiles to the east of that), is that WAD? Now that flipped tiles stay "neutral" for the duration of the rise of the new civ, it screws over whoever owns Athens a bit.
I think and hope, the flipping causing a 'permanent' neutrality is not intended (bug), as Arabia and in fact all flips now do that and as for Arabs in my experience they keep doing it well into 820 when the English arrive so far, which is like 30 turns laters from 632 when the flip occurs. I'd expect culture would've had to build up again in that square from zero when it is near a city they not even control, remotely. Same else happens to Tyrus for example, though there a lot is sensible taken by Arab rise.
