When you place a sculk shrieker down in creative mode or survival mode, and walk over it a bunch of times even when sculk sensors are right next to it, the warden will not spawn in. This I am trying to do on the surface, not in the ancient city. the ones that spawn in the ancient city naturally work just fine, it is only the ones that I break and re place down or that I place down from the creative inventory. Even placing them down in the ancient city they will still not work. ONLY the ones that spawn naturally in the ancient city will spawn the warden, not the ones placed down by players in ancient cities, and not the ones placed by players on the surface.
