Just had a huge pack of zombies spawn on my Mushroom Island when I slept. Checked the coast, it all seems to be part of the mushroom biome. Attached are screenshots of the "zombie raid" happening and another one with the F3 and Seed data.
I'm on 1.16.1 (Realms) as seen on the second screenshot.
[media][media]Mushroom island
Player and iron farm inside the mushroom_field biome
(the only area in the cold_ocean biome is marked by torches in the back of the image, every block around the iron farm building is within the mushroom_field and mushroom_field_shore biomes, every block on the island not in mushroom_field is either torched up or has carpet on it and are nowhere near the iron farm building, I saw the zombies spawn on the blocks within the mushroom_field biome)Minecraft Java 1.16.4
Beds on the island: 7 (6 within the iron farm)
Villagers on the island: 12 (6 within the iron farm)
Zombie siege happened at night
Was going to report the same bug!
