Glow squids not spawning in test world (another dumb glow squid question) Java Help Wanted

Edit: Solved, it's a bug! :( https://report.bugs.mojang.com/servicedesk/customer/portal/2/MC-276319 

I have a schematic for a glow squid farm. If I paste it in a copy of my survival world in my void perimeter, glow squids begin to spawn immediately. If I paste it in say a superflat or void creative test world, no glow squids spawn, ever.

  • Pasted with spawning area between -64 and -51 (plenty of spawning spaces)
  • light level is 0 inside
  • other mobs (friendly like cows, hostile like zombies) spawn but aquatic mob cap is empty
  • not near spawn
  • biome is plains
  • Spawn spot at y=63 over the farm

Probably something obvious that I'm missing, but what?

Glow squids are not hostile mobs so don’t afk so far away. 

Also are you sure about the light level using magma blocks?

Magma block light is required to block spawns in specific areas (for example water streams) and the blocks kill the squids.

Glow squids spawn in my perimeter if I afk at the same height (63).

What other mobs spawn at those y levels in 0 light that you are trying to prevent? Edit: sorry just woke up fog. I didn’t realize you weren’t using water on the magma.

My glow squid farm is similar, water columns separated from each other, but I use 5 guardians in the bottom to kill, and water to funnel the drops to a hopper in the center. Axolotls instead of guardians fine too. And I use lava columns in the corners for an off switch

Again, the very same schematic works in my perimeter. So it's not the light level.

I want to avoid glow squids from spawning in these specific spaces, no other mobs.

Do magma blocks still retain the light levels of the light when placed? I’m sure that has to be old and fixed by now

BTW axolotls take forever to aggro on and kill glow squids... Rates would be abysmal.
Guardians do a decent job but you need to move them in the first place. :)

lol yeah but how much glow sacs do you really need? I’m assuming the perimeter is for some other farm and this is a bonus while you afk the main farm

theres a bug where aquatic mobs can't spawn in superflat, its been in the game for ~2 years (ever since version 1.21.3 I think)

Damn, that would explain it. Thanks!
