When I log in(if I even can) most copies just crash before loading 100%, there are certain places I can go to and all living things disappear, I can’t die and respawn, can’t access inventory, can’t do anything.  My save file pic doesn’t update.  This happens to all my copies of my world, which is about 6.  This started yesterday when I updated to the newest version, which was also the day I found the nether fortress.  Minecraft is ruined, I need help guys please omg! Plenty of storage on phone, checked all the video options and turned off, restated phone, phone is up to date, nothing helps!! Please I have like 40 hours into this world!
