Warnings and Tips

Active collection required: Your platforms lie entirely outside the 32m wandering sphere. Mobs will not walk on their own. Use water flushing or portals.
Configuration optimal: No overlapping dead zones or structural obstructions detected. Spawning platforms are fully within active ranges.
