Enabling Multiple Armies on the Battle Map

[Jmonstra]

I've been running into this issue for the last few battles. Whenever I'm attacked by more than 1 army at the same time, I have to destroy a certain number of enemies before the other armies are allowed in to the battle map. I recall that this is a simple fix involving just changing some values in a text file somewhere, but I can't remember where it is for the life of me. Does anyone know where this file is? Thanks muchly!

Okay so I figured out which file it is (medieval2.preferences.cfg, for anyone else who's having this problem), but I've hit another snag: Every time I modify the unlimited_men_on_battlefield value from 0 to 1 it immediately changes back to 0 as soon as I start the game. Does anyone have any ideas as to why that might be?

Right click the prefernces.cfg and change it to read only, worked for me.
