• This is what may be intentional, but release notes and Minecraft-Wikipedia do not mention this. In the snowy tundra biome and snowy mountain biome, the only hostile mobs spawn are the strays. No other monsters spawn, such as zombies, spiders, creepers or even skeletons spawn, which in the Minecraft Java edition can spawn normally in snowy tundra biome. These day I have checked the file of ice plain biome and ice mountains biome, and I found that there is a 'frozen' tag in this file, which controls the spawning of the strays, but no 'monster' tag in it, which controls the spawing of the zombies, spiders, skeletons and creepers. As far as I am concerned, it must be a negligence to have omitted the 'monster' tag, causing there are only strays in the snowy tundra and snowy mountain. I hope this bug can be fixed as soon as posible. Thanks for your attention.
