Game crashes when it is the turn of the Roman faction.

I have been playing with the Koine and the Sweboz and there is a time in the game when it is the turn of the Romans and suddenly the game crashes.

I tried everything, and it cant be fixed.

I followed the guide before posting here and still doesnt work.

it always happens when it is the turn of the Romans.

all my cities are green faced.

Here are my saved games.
