I had same issue but with pants. The only way I found to fix was exporting a character that is fine, then importing that onto the broken character, then you can re-customize them.

hi Enlit3D, it looks like there's something wrong with the new patch, some of my characters lost their arms. Please fix it!

Is the winner being able to have their way with the loser planned for the future?
