Ever since I downloaded the OFFICIAL 1.16.1 release, my main minecraft world has been CORRUPTED 3 TIMES. I have no idea why. But it feels very very random. I have had to make backups many times in the fear of losing lots and lots of progress I make. I sign for when the world might have been corrupted is when the player stops gaining xp even when they should be gaining it. IF YOU EVER NOTICE THAT U ARE NOT GAINING XP, make a backup of your world right away!!!!!!! But yeah, my issue is VERY PROBLEMATIC.
