That sounds like your client failed to load those assets for some reason. If it recurs, let us know. You could try clearing your browser cache, in case a corrupted asset go loaded somehow.
The AI human priest skin is listed in the wrong place at Cuthbert's Costumes if the dropdown lists are set to Any+ Any or Priest + Any. It's listed between dwarf wizards and elf priests, which is confusing. Ah, I figured out why. The skin entry is in the wrong location in the Figures.csv configuration file.
Even more disappointing when you figure the Half-Elf Cleric is an elven costume until you get it. $E^ b (It'd be cool flavor to use for either human or elf, but understandable for multiple reasons to keep it human-only. Oh well. Heheh.)
I couldnt find a more appropriate thread for this so decided to stop here. I have seen this bug on the forums a long time ago - about 6 months ago. Spoiler: Screenshot Can anyone explain why this happens? Note: The figure went back to normal at the start third match.
