@tralala Oh yes I just came across your video on YouTube ( such an accurate recommendation LOL), and thank you again for solving the mystery!

Oh and, what's a little bit different in my case is that, I have some squids spawn in a river just next to the farm, but is far fewer than what it used to have. I have an assumption that now the spawn condition of squid may require the water to be exposed in air? Otherwise I can't figure out another reasonable explanation.

Hi zaSami, I came across the same problem on my server, I'm using PaperMC-1.18-52. And I tested on a vanilla 1.18 single player map, it still does not work. I had been using this farm since 1.17.1, and it worked really well. I built it from exactly y=50 to y=64 in a river biome. Had you figured out what's the cause is?
