Ending turn causes an infinite loop when it tries to calculate the AI's turn.
I will explore it in more detail, and give my findings soon, but help would also be appreciated. (Also, there is a MASSIVE bird in the SE of the island!! Didn't know about that...
[Edit] THe big bird is just a Roc. However, I have traced the lock into the Basileraphs nation. Killing all thier cities stops the lock. However, killing all thier units, all thier cities, and WBing one new blank city DOES cause the lock, which implies to me like it is some sort of diplomacy problem, and not a problem with city management or pathfinding.
I may be wrong however.[/Edit]
