I was flying around the other day on the server looking for gravel. I remember that it was day time. And yet I saw zombies, skeletons, creepers and endermans popping up out of nowhere. So I am wondering how this can happen since it is day time and no other players are online. Next question regarding this subject. Why is it that when I am the sole player online and I am in the nether dimension I only get 10 pigmen spawn max. I have enough spawning spaces. I am 128 blocks above the bedrock layer so that only mobs can spawn in my farm. Yet only 10 spawn max, while when I was testing in single player I got a continious stream of pigmen ready to die. I got 2 chests full of items in under 10 minutes. Now i am lucky if i get 2 stacks in that same time frame. For those wondering how my farm looks, I based my design of the farm built by the genious pal called Ilmango. He has a tutorial on youtube for a simple 1.12.2 gold farm which is supposed to give 115 k XP per hour. I am only getting 5 k XP per hour is my estimate. I hope there is a bug somewhere on the server because something is clearly not right. I know it is SMP so that spawning works different and you share a mob cap with others. But this is just insane. I have 12 pigmen around my farm with name tag so that they won't despawn and that they will aggro trigger the new spawning pigmen. In my opinion this farm will not cause any mittens. Because the amount of stress it puts on the server is probably even lower than a couple of spawners spawning blaze. The gigantic nether portal spawners are way worse because they have to be linked to a portal in the nether and they generate a ridiculous amount of particles while I only get death and xp. Hopefully I can come up with a fix togehter with Devs and admins. Because I think I am not the only one with this problem. But there is more, I was building a platform around a fortress so that wither skeletons would spawn. I know this work is tedious, even with looting 3 you need to kill about 12 skeletons to have a 50 percent chance of getting 1 skull. I got about 5 skulls and then the most abnormal thing happened. I killed 50 skeletons approximately without getting a single skull, I knew this because of the statistics in minecraft. When you kill 50 skeletons you have a 90 % chance of getting a skull. Of course you are not guaranteed one ever. But 100 skeletons without a skull is almost impossible. So is there a maximum of skulls you can get per hour or per day because I was not getting anymore after the 5 I got previously. Hopefully someone can shed some light upon my questions and help me out here. Happy Diamond hunting greets, Coolmattie Edit #1 I have found the website with the wither skeleton graph again. The purple curve is the probability of a skull dropping. L is the level of looting, K is the amount of wither skeleton kills and S is the amount of skulls that have been obtained. I have killed at least 55 without getting any. So lets take my 55 as an example. You have an 80 % chance of getting 50 skulss within that 55 kills. and a 95% of getting 1 skull. Here is the graph for anyone to play around with https://www.desmos.com/calculator/zqynwkb98z Edit #2 I think the issue lies in Spigot, since more things tend the break when Spigot is running. But I believe the issue can be sovled by using the right settings. I could play around with it for a bit I guess. Edit #3 Just to be clear, I am not hating on any individual or group. I am just so frustrated that I have to spend hours to build and research and modify a farm. Only to find out it works for 10%. I heared from wazoomie in the past that he was looking into a mod which groups mobs together in packs. For anyone who plays modded. Compressed mobs, these were very common in certain packs. It is like 9 zombies grouped up into 1 compressed zombie. When you kill the zombie you get the rewards of killing 9. Something similair like this would be an improvement already.
