So i started playing in world "A" while you were working on the new 1.12 update (i was playing in snapshot versions).Everything was okay until i made one of those AFK fishing farms.I don't know if the farm has anything to do with it but i am just saying what exactly happened.After the first two-three AFK
sessions i noticed that a chunk in my world had changed(it had been a river chunk but it had turned into a forest one).Anyway i thought it was because of the snapshots as they are buggy and stuff..but as i kept playing 3 more chunks changed and this was really scaring me as all of them were close to my base.. Last week when i tried to enter my world, the game wasn't showing me world "A" in the list of worlds.The world folder was still in my saves folder which means that the game wasn't recognizing the world (aka world corruption)..I started a new world(this time decided to avoid playing in the snapshot versions and downloaded 1.11.2 as it was more stable and reliable).I set up a starter base and when i logged in today i saw the same bug that was occurring in world "A"... two chunks had changed themselves.I have no idea what is going on and how to stop it.Any help is appreciated!
