I've made this wither skeleton grinder on my friends multiplayer server and its not working as intended.
I've been told by the person who made this design that its because its a multiplayer server, but it doesnt work even when no one is on the server but me. The entire nether fortress is covered in buttons as it should be, and barely anything spawns inside the grinder. On top of that, the piglin used to attract wither skeletons keeps disappearing despite being name tagged (this has happened 4 times now). I really dont know what else to do here so some help would be really appreciated.
I dont see any way the piglin could be getting killed
I had someone check in the box in spectator while I was down below, wither skeleton cant seem to reach the piglin and blazes dont even target them. Magma slimes cant spawn in the box and zombie piglins get filtered out through the corners.
I haven't spawn proofed the area around the fortress but im positive every block of the fortress thats exposed has a button on it. If blocks are above the fortress could fortress mobs still spawn there?
I dont believe any plugins could effect this either. All we have is maptool, and some kind of plugin that turns to day when only one person uses a bed rather than all players having to.
The fortress is in a soul sand valley as it said it should in the video. I guess this is because less mobs spawn there??? However, a couple blocks of the grinder are technically in a crimson forest but I dont really see how that would change anything.
Sorry for the late reply. I'll try to explain this as simply as possible. There is a mob cap which means that only a certain amount of mobs can be present at one time. Named mobs do not count towards the cap. Mobs will spawn in a circle 128 blocks out in each direction even if you can't see the mobs. Judging by the comments your grinder is near a crimson forest which will effect your grinder greatly. Mobs ARE spawning in the crimson forest and taking up the mob cap. Definitely something to worry about.
As for the Piglin thing idk man
Edit 2: Found out the Piglin thing is a bug, nothing's wrong with your server. Hope it gets patched soon
