Hi, I might found a bug on 1.18 pre 4 regards squid spawn.

So I did a Squid farm in a river biome, drained all rivers/beaches/oceans/lush caves near me 128+ blocks.
I've did a big "pool" in my river biome to see if any squid spawns. no squid spawned for more than 1h there.
I searched with spectator any squid near me even tried to kill @e type, and no entity.

Then i went to single player to see what's happening. I used fill commands to dig a very big hole in 2 different biomes (river, ocean) and drained all water near me.
No squid spawned in the box that i created nor in river, ocean.

But when I fly with creative random in rivers that are not that "spacious" as my 2 holes that i dug with fill commands, they spawn.
This is very weird, I don't know exactly what is this.

Thank you,

zaSami
