Problem with entity exception in version 1.20.2

[aweibuome]

Expected behavior

Normal number of entities

Observed/Actual behavior

Too many entities, including cows, sheep, water creatures, zombie, and so on

Steps/models to reproduce

When I set the per-player-mob-spawns option in the paper-world-defaults.yml configuration file to true, although the server only has a few players online, the number of entities in an area has reached an astonishing 20,000 , cows, horses, and squids everywhere, it is impossible to kill them all. This problem does not exist in version 1.20.1. The monster spawning limit in the Bukkit configuration file is the default. When I set the per-player-mob-spawns option to false, the number of cows and sheep began to return to normal, but the refresh frequency of monsters was relatively low. This is the picture when set to true

1.20.2 Is per-player-mob-spawn optimized? Does this option have to be disabled? If it is not disabled, the number of entities will be abnormally large, but there is no such problem in 1.20.1

[MineSunshineone]

same maybe paper problem

[sofianedjerbi]

Does this still occur on latest commit ?

[aweibuome]

Yes, when I ran the last submitted kaiiju server, when I set per-player-mob-spawn to true, a large number of creatures still appeared. The following is the picture

[sofianedjerbi]

I can't reproduce this issue, is there any extra information ? (Biome, conditions, number of players..)

[aweibuome]

I don't know if this information is valid for you, when I upgraded to 1.20.2 for the first time（ about two days ago）, the number of entities was very large, and when I tried to add some content on the number of creatures in kaiiju-entity-limits.yml, like GlowSquid: limit: 500 removal: 600, Something happened, I can’t open the launcher, this is the error message ---- Minecraft Crash Report ---- // Daisy, daisy...// DO NOT REPORT THIS TO PAPER/FOLIA!

Force Loaded Chunks: {} Server Running: true Player Count: 0 / 88; [] Data Packs: vanilla, file/bukkit Enabled Feature Flags: minecraft:vanilla World Generation: Stable Is Modded: Definitely; Server brand changed to 'Kaiiju' Type: Dedicated Server (map_server.txt)

I deleted the configuration file and regenerated it, but it still didn't work, and I still got this error. So I opened a new archive and copied the world folder, world_nether folder and world_the_end to the new archive. Fortunately, it can be opened normally.

Some other additional information, the number of players on the server is about 10, and each player joining will add about 3,000 entities.

bukkit.yml: spawn-limits: monsters: 70 animals: 10 water-animals: 5 water-ambient: 20 water-underground-creature: 5 axolotls: 5 ambient: 15 chunk-gc: period-in-ticks: 600 ticks-per: animal-spawns: 400 monster-spawns: 1 water-spawns: 1 water-ambient-spawns: 1 water-underground-creature-spawns: 1 axolotl-spawns: 1 ambient-spawns: 1 autosave: 6000 aliases: now-in-commands.yml

I don't have any more information because I made almost no changes to the other configurations

The current solution is to set the per-player-mob-spawn option to false. After setting it to false, everything on the server is normal. This is a normal picture.

I want to know if other people who use kaiiju1.20.2 have the same problem as me. If not, maybe there is an error in my own archive,and you can close this issue.

我想知道其他使用 kaiiju1.20.2 的人是否和我有同样的问题。如果没有，也许我自己的存档中有错误，您可以关闭此问题。
