Thank you for responding!
This ticket isn't a duplicate of MCPE-153942 because that ticket reports the intended feature of not spawning Wardens from Sculk Shriekers placed by hands while my ticket is reporting the inability of spawning Wardens from natural Skulk Shriekers placed by outside methods.
I have found a work around for this issue which surprisingly the first method to reproduce, which turns out it didn't end up with the same result as the second method. sorry for disturbing
i think the first part is working as intended, but the second part is a bit problematic, it need to be fixed
Mojang could you please fix this bug soon in 1.16.230 or 1.17 , it's affecting my skyblock map and my friends need slimes spawning again
i tested this bug and i am very sure it's true
no slimes spanw in flat world neither in slime chunks nor swamp boime
This issue isn't fully fixed yet, slimes still can't spawn above y=0 in flatworlds
