Game crash around year 417 & 420 (turn 90 to 101)

Hi all,
I am using the following mod in the following order:
10 AEP FOTA mod pack
Fall of the eagles 0
Fall of the eagles 1
Europa Perdita

I have been playing with 2 saves.
First one is Rome and it was all fine until year 417 turn 90something.
This save couldnt get past this turn as the game will just freeze once I click on end turn.
This freeze is before Attila became the King event. But the game freezes on a very minor faction.

I then started a second run.
Now i got to turn 100+ year 420 and after an epic battle the game crashed.
I cannot load that save anymore as the game just always crash before the loading bar could finish loading.
I went past the Attila became the King event this time.

Any ideas?
Cheers.
