It's a bad idea to disable starting settlers for the Turks (they are commented out both in the section where it spawns military, and where it spawns workers - is it a bug? And why do the settlers were supposed to spawn with the workers, as readme says?) Their units wander inside the Asia Minor square free of Byzantine culture for two initial turns, then the Byzantine culture closes on these tiles again, the Turks are teleported to Crimea (If Crimea were settled, they'd perhaps teleport to Central Asia, which would be sort of funny), and then I was greeted with the "cede cities or declare war" popup. Awkard.
