You are incorrect. while it's entirely possible that it was just a bug that was allowing them to spawn, she's only ever played the game in creative with the ability to build whatever you want without gathering anything and there were bugs when she first started playing, I saw them first hand. They went away after the last big update. We only play on Xbox so there are no mods you can use. So even if it's unintentional, they need to enable them in creative. Some people just like to build and having NOTHING alive in the work just makes the game boring. This game is in preview and they want feedback which i'm providing. I'm asking them to put bugs into creative mode to make the world feel alive for those that like to free build.
