On my own system, I have compiled a group of mods that work well together.
I've cobbled together FPS tweaking graphics, some sound mods, and the BAI component of Darthmod.

All works well on my computer, but when I try to install them on my girlfriends system, she experiences a strange discrepancy.
On HER system, when besieging a castle, her archers do not function correctly. Their range markers don't show, they do not get range cursors when passed over potential targets, and they seem unable to begin firing on most targets behind the walls.

I'm considering that this is a byproduct of DartMod BAI, but before I go much further, I should check to see if this is a known issue. I can't find any threads yet...
