A New Type of Monster

Now I present to you guys an important question regarding my frankenstein creation, the MedMod XL. I basically took Medmod and added all of XL's extra factions to it (the cumans, portugese, Lithuanians, etc). The game starts up and the campaign map runs fine, but the new units from XL for some reason are cannons, trebuchets, and other sorts of artillery. Also, the game crashes when you go into battle mod. Thanks In advance

First of all, have you asked Wes and VH before you did this thing?!

And second, check the Repository guides, it helps you at everything you need to know.(well, almost everything)
