For some reason, every time I rejoin a singleplayer/multiplayer world, they just disappear. Now, I understand this has been issued a few times before, although I’d like to know why it just doesn’t work. Did you never resolve this issue in the first place? This seems weird because in Popularmmos Epic Proportions Season 9, they are playing 1.7.10 and their morph and hats mod works just fine.
