    Description

      The bug

      Zombie reinforcements can spawn on the following biomes: Mushroom Fields, Mushroom Field Shore, The Void, and all Nether and End biomes, even though zombies naturally don't spawn in those biomes.

      Steps to reproduce

      1. Create a single biome world of one of the previously mentioned biomes, on creative mode.
      2. Set the difficulty to Hard.
      3. Set command blocks to constantly kill any mob that is not either a zombie or the player (you cannot execute the command /gamerule doMobSpawning false, as that disables reinforcements). This is not necessary, but it assures that other mobs won't interfere or attempt to kill the player.
      4. Set the time to night.
      5. Spawn a zombie that can summon reinforcements inside it:
        /summon zombie ~ ~ ~ {Attributes:[{Name:"zombie.spawn_reinforcements",Base:1.0},{Name:"generic.movement_speed",Base:0.0}]}
      6. Switch the gamemode to survival, and hit the zombie a few times.
      7. Zombie reinforcements will spawn.

      Expected results

      Zombie reinforcements should not spawn in biomes where zombies can't spawn (especially in the void).
