When I load up with mpm and armourer's workshop on 1.12.2-0.50.5 it doesnt allow my HD skins to show on my player and none of my saved skins show up. it defaults my skin to the skin i have on without mods.

Sorry, 1.7/1.12 is no longer supported

I am also having this problem! It's not the biggest deal but it's slightly annoying :(
