I may have mentioned some of these already, sorry if I have. I got a msg after hooking up the gold bar icon for spices. It said I could make some new units now. I could not find the icon in the resource pedia and the spice one did not list a unit I could build. Going to the pedia for Resources, you get 4 items. Bonus Lux Index Strategic. For Bonus you see a Wheat icon. Open the link and find only Sheep in the list with a different icon. Lux has no underlying entries. Going to the city view and right click on strategic you find Horse, Iron and Salt. Horses 0F 0S 1C, gets hyperlink exceed, but goes on. Sheep give 0F 0S 0C? Not much of a bonus, if the pedia is correct.
