Allied race character portraits currently show up as a blank box on the character list.

Not an incredibly important issue, and it's one I'm sure you're already working on, but it has been nearly a month since allied races were released.

I managed to fix this by modifying players.lua in external/Wildpants/core/ to use the same icon selection as worgen, goblin and male pandaren

Line 19 was:
if race ~= 'Worgen' and race ~= 'Goblin' and (race ~= 'Pandaren' or sex == 'Female') then

Changed to
if race ~= 'Worgen' and race ~= 'Goblin' and (race ~= 'Pandaren' or sex == 'Female') and race ~= 'VoidElf' and race ~= 'LightforgedDraenei' and race ~= 'HighmountainTauren' and race ~= 'Nightborne' then
