so when I logged into my hardcore world I was wearing diamond armor right? then in chat it said "Cover me with Diamonds", and I got confused. then I checked my advancements and all of them had  reset, even my nether advancements reset. I was not happy because now i have to redo ALL my advancements which I had a ton of. please fix this immediately because some people might have to re-fight the ender dragoon and go to the end again and maybe even have to get another elytra which really sucks so please fix this
