I like huge battles, so i had an experiment...

I made it so you can recruit 9 units in one turn while recieving 9 units every next turn.
Up to turn 7-11 the game always crashes...
I have been wondering if there are too many armies on the campaign map for the game too handle?
Is there a different problem if so state it...
If this is the problem can some one tell me how to make a maximum limit of how many units a nation can recruit, like in RTW, the maximum was 400.
