Attempt made to initialize dimension id 2 which isn't registered!, falling back to overworld

I keep getting this in my console. I have looked and looked to see if there is anything that can help me. But everything everyone has done to fix there issue is not fixing mine. I run 1.12.2 minecraft for pixelmon 7.2.2. I have updated all my mods and plugins to the most recent and I can still get into my server and play no problems. BUt it is driving me crazy that I can’t fix this.

Could you supply a log of your server?

Yes I just have to remember what thing to use for the log so I don’t just paste it all in here

Here’s a list of some paste sites and their size limits:

This is the main reason why you are getting that warning

[08:31:26] [Server thread/WARN] [Sponge]: World [ultra] (72) is attempting to be registered as an existing dimension but it's dimension id has already been registered for folder [null]. This means the world has been copied outside of Sponge. This is not a supported configuration.

The world “ultra”, how was it imported into your server? and where is the world folder compared to the root of the server folder? (for example, the sponge configuration folder would be ‘/config/sponge/’

Also, what folders do you have in the following folder

/config/sponge/worlds

Also, there are a lot of errors coming from GWMCrates, I would advice getting those sorted.

yeah I have a crate that has been giving me problems for the gwmcrates. For the folders its just pixelmon minecraft and biomes o plenty. I honestly don’t know where the world ultra would of imported to. I’ve tried looking but I just haven’t found anything.

is there a folder called “ultra” in the following folder?

/world/

in config/sponge/worlds/pixelmon there is a folder ultra_space

and then ultra_space folder there is a folder called ultra

Based upon your previous messages, you didnt even know this world was on your server and therefore, you wouldnt mind if the world was deleted?

If so then take a backup of your server and then delete the ultra folder. Due to its strange folder location its likely that another mod is loading it in, due to that nature deleting it will either fix the issue or crash a mod/plugin. If the latter occurs then i can find out how the world should have been imported and hopefully make you a little plugin which imports the world correctly

So far deleting that file has seemed to work thank you. Haven’t had that error pop up yet, and my server is still working normally.
