when I imported a skin and my friend did the same, we went on Minecraft and played together. I was my hausemaster skin from 2b2t he was his own. Then, my skin CHANGED TO HIS WITHOUT ME DOING IT and the same happened to him. He also told me that that also it happened on cubecraft with someone else! It started around 1.16. I would really like it to be fixed so Minecraft can return to normal.
