Now my one question, WHY DO THESE BUGS KEEP AFFECTING WORLDS, I have lost BOTH my SURVIVAL AND REDSTONE WORLD to this issue and my previous complaint WHICH  NO ONE  has even taken the time to answer me, I am absolutely sick and TIRED of this, I  HAVE LOST the motivation to even play Minecraft, I have grown to be scared EVERY SINGLE TIME I log Oout of my world, I have created copies AND GUESS WHAT? they get affected TOO, look please just please fix this bug/error that is happening Mojang
