Please forgive me if this is posted in the wrong place. I am unable to find a specific place for help. As my days are opposite to most of the rest of the world, I play a lot by myself and therefore there is no one else to ask. I have a problem with zombie spawner. I made one and put it in the overworld, it works perfectly but does not produce zombies - much like a pigman spawner if it is not in the nether. So I built a dirt hut to make it dark and tried again, with plenty of space: it still does not produce zombies. I have been unable to raise anyone to help with this. Could someone please tell me what it is I have wrong?
Thank you so much and apologies again if this is posted in the wrong place.
