I made a spawning platform, 5x5 with a grinder in the end. I put down a chunkloader and made sure that the right chunks were loaded. When I go back in the overworld, the enderpearls are not going into the chest. Apparently, the endermen do also not spawn when I am directly near the grinder, and neither when I walk too far away. I need to walk to specific range to make the platform spawn endermen. My question is, how do I make sure that endermen spawn there, when I am located in the overworld.
