Hmm, you're right. That was utterly bizarre. I repackaged the file on my computer, deleted and reuploaded it to mediafire, and downloaded it myself. It will now work as intended.
As for the Manden King, I compared the cultures.txt from SWMH 2.8 and CPR and BLG and "Manden" is the word that appears in all of those files. Project Balance is the only mod that calls it "Mande", and you're not playing with Project Balance, right? Otherwise, I don't know what would be causing that graphical bug.
