      Description

      I was trying to get custom biomes to work in a datapack I'm working on. I noticed that there was an error in the console, saying that there should be a name at the start of a list under the creature compound in the spawners compound in a custom biome's JSON file. I changed it such that the list went "minecraft:cow":[<the rest of the list], closed and reopened Minecraft, installed the datapack while creating a new world, pressed done to get it to validate the packs, and...freeze.

      Here's what seems to be the important bit of the log:
