If this is something that only affects some regions then it's logical to deduce that this has been caused by an administration issue with those affected regions and all of us who have been PAYING for a realm on these servers should be compensated for not getting what we have PAID for.
Same issue on both XBox, Win10, and MCEarth. Customized skin will reset to either Steve or Alex and then has to be recreated. Honestly getting sick and tired of having to recreate what I look like. What is the point of having skins when we can't reliably use them?
Happening again in 1.13.1
All skins have vanished again today ... they were there yesterday but today everything is back to Alex and Steve. What is the point of spending time creating characters or purchasing skins when they just randomly get deleted?
