you can download the appx of Minecraft,then you can open and update easier
so the two world is the same if you try, I can’t offer a stable save only if you can use old client
well,this happen everytime you reload a world instead of update world,more negativer :(
@GoldenHelmet
I dont know which part of my expression make you confused,video shows that the top core can’t continue to generating basalt after firstly push when piston begin to pull and push,you can see lava flow to the place above soul_soil and between blue_ice but dont generate basalt.As I say in Description,the station of lava_flow will continue existing(dont switched by basalt) isn’t it is a abnormal thing?I think I have read the wiki carefully):
