Playing in version 1.19.3, super-flat world, creative mode. Some villagers I bred in a while ago (maybe in version 1.19.2) have messed up skins. Kinda looks like the villager and iron golem skin mashed together. I logged out of the world and logged back to find the skins changed. They aren't fixed, just messed up differently.

(Second photo is when I logged out and back in.)
