im using the AUM mod (http://www.twcenter.net/forums/showthread.php?t=250655) and everything is going fine. however, whenever i try to use blunderbuss shotgunners, it always crashes upon loading the battle. how can this be fixed?

also: all grenades have been taken from the mod; it said how to add thme back in, but it showed only prussian giant grenadiers, and elite euro grenadiers. are there any other normal grenadier units i can add greandes to? and where?
