...except, as I just realized, the unit card shows a peasant in a black shirt, and it holds no unit description.
This is kinda weird, 'cause I un-paked and added UNIT and UNIT_INFO for the relevant units from the folder "mercs" in the "pack" folder to my greek_cities UI folder (yes, lots of "folder" in that sentence).
I haven't had any problems with peasants on unit cards since I downloaded xpak and started using it..hrm. Any suggestions?
