Denizen fails to load on 1.21.8 https://paste.denizenscript.com/View/135768 using USpigot, but seems like this would likely be an issue on Paper as well. I can test that shortly if necessary.

Hi I'm AutoThreadBot! Don't mind me, I'll just be adding the helper team to this thread so they can see it. A human will get to you soon.

Info: logs

Please post your full latest log file.

Background Info: One of the most helpful tools to identifying the source of a problem is your server logs file! Logs contain all sorts of important information like server and plugin versions, any error messages, and a lot more important information (More Info).

How To: Your log can be found in the logs folder within your server folder. The most recent log is a text file labeled latest.log. To get help using these logs, please open that file in a text editor and copy all of the text, then open https://paste.denizenscript.com/New/Log and paste the text into the box on the page. Then click "Submit" and copy the URL and paste that back into this channel.

Please do not upload the file to Discord or to other pastebin services, use the log pastebin linked above.

Can you provide a full log.

I think I see the issue but let's be 200% sure.

(Pay no attention to the amount of other errors, working on updating my test server to 1.21.8)

Server Version

UniverseSpigot version 1.21.8-ver/1.21.8-stable@617c5f0 (2025-08-19T07:51:19Z)

Plugin Version(s)

Denizen v1.3.0-SNAPSHOT (build 1804-REL) -- (Current build :white_check_mark:)
Depenizen v2.1.1 (build 882) -- (Current build :white_check_mark:)

Checked For

@astral flint

Online/Offline

Offline, but proxied.

Java Version

21.0.7 :white_check_mark:

Other Noteworthy Plugin(s)

WorldGuard v7.0.13-beta-2+5c4848b, MythicMobs v5.10.0-SNAPSHOT-ee9efe77, ProtocolLib v5.4.0, Quests v3.15.2-5b4752e

Possibly Relevant Plugin(s)

ViaVersion v5.4.2 - Mixed client vs server versions can sometimes cause packet-related issues.
HeadDatabase v4.21.1 - HeadDatabase has been known to cause issues with skins.
ModelEngine vR4.0.9 - ModelEngine has Citizens support, but that support is known to be buggy. Issues related to NPCs that use ModelEngine should be reported to ModelEngine support, not Citizens.
FastAsyncWorldEdit v2.12.4-SNAPSHOT-1010;e0db69c - This plugin has been known to break the plugin load order on many servers, due to usage of the 'loadbefore' directive in its 'plugin.yml'.
GSit v2.4.2 - 'Sit on other players' or 'sit on mobs' plugins sometimes allow players to sit on NPCs.

Potentially Bad Line(s)

Starting Minecraft server on 0.0.0.0:25565 - server is offline but has no address bind. This might mean you're using a system level firewall, but if not, it means your proxy is bypassable by hackers. Either enable a system level firewall, or bind your server to localhost in server.properties via server-ip=127.0.0.1.

Well uh.

Firstly, I don't know what universespigot is but.

#

!forks

# astral flint !forks
Info: forks

Our plugins (Citizens, Sentinel, and Denizen) officially support both Spigot and Paper.
Any other forks of the Bukkit project are not supported, but may or may not work in practice.

  • Lower forks, like CraftBukkit, do not function. You must upgrade to a higher fork (Spigot or Paper).

  • Hard forks and cross-forks, like Cauldron/Magma/Mohist/Any other Forge-integration fork, or Cardboard/any other Fabric-integration fork, will not work. Some unofficial custom builds of Citizens are made to support these servers, but we cannot provide any support for them here.

  • Higher forks above Spigot/Paper, such as Purpur, Airplane, etc. are compatible with Citizens only as much as they are compatible with Spigot/Paper. They are generally expected to work in most cases, but we cannot make any guarantees. We will still offer support to users running such forks, but be aware that if you encounter bugs while running such a fork, we may ask you to replicate them on Spigot/Paper to confirm they aren't caused by changes the fork made.

But that isn't the issue.

#

The issue is the last release for Denizen only supports up to 1.20.4.

#

You'll have to get a dev build.

#

!update denizen

You are totally right, I swear I clicked that. Lmao, thanks so much

astral flint
#

If the issue still persists then it might be a fork issue, but dev build should work on 1.21.8.

#

Where is UniverseSpigot??

#

I'm trying to find the page to look at uspigot.

#

I cannot find it.

#

Like it's not relevant to your problem, but I want to know where to look at this.

#

It's just a heavily optimized paper fork, don't believe they have a website, MachineBreaker is one of the maintainers if you know who he is

astral flint
#

Can't find the repo on their git, weird.

#

Either way.
