I think this issue should be expanded .Because this bug is not only limited to Nether,It also happens as stated above.
I just checked the Old World in once. I didn't find the chunk bug in this type.But I don't sure whether it exists in Old World or any other dimensions from mods.
This bug also affected Flat World.MCPE-141727 was reported that hours ago.
AND do the files attach with Experimental:Caves&Cliffs?
Is it similar to MCPE-140436?
Once I met 2 trees ,one was outside in land,when you dug down,you could find another one.
I think It can spawn in any space in overworld
I just randomly checked some of coordinates without Experimental modes.Results completely different!!
[media]1.17.30.24 Beta is also affected
Same world file and same day I found this bug after I'd found MCPE-141189
Ores should be spawned in rocks/stones or relied on rocks/stones.
(the chunk bug as same as in the nether)
I just go to The End by putting the End portal.Then I went to the center Is. with a dragon.I'm sure it was normal(true generating).Then I teleported to(10000,99,10000) to sure "MCPE-140772",it's true,but as I return to (0,99,0) by "/tp" , the same bug reappear in Center Island.
