I assume this has probably been noticed but.....
The categories in the unit design window are horribly wrong.
Under the Armour Tab, I'm fairly sure that cloaks do not count as "Wrist Gear" and that Armlets are not "Weapons"
Under the Equipment Tab, Boots count as "String not found", and again cloaks as "Wrist Gear"
as an additional bug, the first time you go in to the screen after a reload, the items aren't divided into categories at all.
