Ok, obviously this is not a gamebreaker by any stretch.  It just bugs me every time I see it.  The equipment tab in the inventory is labeled "Equipments".  There is no word "Equipements" in the English language.  Don't take my word for it, though.

It just makes the game look like it has poor localization.
