When I try to summon a million of Piglins with the "/summon Piglin" command on a repeater command block, and set to always active, it won't summon Piglins or any nether mob in the nether.
How to reproduce :
- Go in the nether.
- Place down a repeating command block.
- set the command block into always active.
- write "summon Piglin" in the command slot.
- Exit the command screen, and no piglins will appear by the command block.
If it works for you, put down a comment.
PS: If you have trouble with the infinite summoning, put another repeating command block and set it to always active, and type : "kill @e". Make sure you're on creative.
