I decided to play minecraft dungeons today (of course) and the game was much slower than usual, so I decided to turn off and turn back on my laptop, when I came back in, the crash screen came up, I closed the page and then I went back on to the game, when I came in, the game was completely reset, it showed that I didn't have any hero, it showed that I haven't even touched any skins.

note: I don't know what versions are affected, but I was on the latest version
