Hi, it's not just the copper, your coordinate shifted 64+ Y coordinate... You may find other bugged stuff, like chests, shulker boxes, they will be empty, double chests will be single chests and wiped.. Potions on cauldrons will be water in cauldrons, any head will be a skeleton skull, sticky pistons does not pull blocks unless you break the block an put it back, banners will be wiped, meaning they will be gray/black. Item frames will be wiped.. Atleast that's what happened to me but idk if it happened to you.. Your chests is fine.. Hopefully the rest will also be fine... But your coordinates has shifted i assume... Or are you on a mountain? 

What is your tick speed set to on your world? 

Hi, i once had that on my old phone, and it was the sweat on the screen that came from my fingers, so i puased my game and cleaned my screen, if it still does that auto walking after you cleaned your screen properly then it is a bug, I'm just saying that that happened to me cause of that i explained. 

Ok, just checked.. Yes it's the tick speed, i think the new update might be big enough to slow the mobs in the nether.. And idk if it's just in the bastion remnants.. If it is and someone knows, then pls reply cuase I'm seriously not gonna check it.. It might be an old thing, i might have not just saw it before. 

Sorry for the typos 

100,but on the other versions it was on 100, and it worked smooth. No slow mobs.. On the older versions, my the mobs would walk slow if the tick speed was on 800

um translation?
