With the Danny expansion mod is spawned some over world desert related like the mummy and black scorpion, with Alex’s mobs when spawning like the gust or tarantula hawk they stay as overworld looks when I spawned instead of the nether relates and another bug not similar with this topic but the mushrooms get angry and attack on creative and spectator mode
