You are currently using Java 19, use Java 17 by changing the PATH environment variable or by using the absolute location of the executable.

The version you are using is no longer supported on this forum. Please update to a modern version of Minecraft to receive support. Currently supported versions are 1.19.3 (Latest), 1.19.2, and 1.18.2 (LTS).

You can use spark to profile the server whenever the load increases to see where the performance slowdowns come from.

You could use rubidium or oculus/iris, though I don't think it should matter either way.

I didn't even know that there was a curseforge release. I just knew about the Github. I'll ping illy about it.

They are generated the same way as regular ores, so yes, you can control it.

You can't perform an equality check on stacks. They are mutable and always changing, so they are unlikely to be the same. You should check if the item in the stack matches your item (via ItemStack#getItem).

There are cases where the section hasn't been generated yet. As such, you would need to perform numerous safety checks. I would look at OreFeature and BulkSectionAccess for examples on how to safely check the block state of certain blocks.

Probably an issue with the YoureSeeingDungeonsMod; try removing it.

Please provide the debug.log from the logs folder in the game directory in a pastebin or gist. Preferably one from the server and one from the client where the action has taken place.

Try removing OptiFine; that mod tends to play horribly with others and usually Forge itself.

So the configured feature just modifies the maximum size of the veins. The placed feature determines how many spawn, at what locations, etc. If you want to reduce the size of the vein, modify the number in the configured feature. If you want to reduce the number of veins, modify the placed feature. The placed feature that modifies the number of veins should usually be the first one on the list. The Minecraft wiki has an entire section on what each type does.

Remove OptiFine, it is currently not compatible with Forge 1.19.3.

Why can't you access the mod folder?

Could you please provide the entire debug.log in the logs folder from the game directory in a gist or pastebin?

They are different things, but you should be able to get one from the other, so there is no issue.

Create a block. Just look at any kind of ore in the Blocks class; it is the same exact process. The rest is just the features which are the json files.

No, swamps just spawn slimes naturally. If you wanted to modify how slimes spawned in swamps, you would probably need to change the information associated with the spawn placement of the entity itself, which is currently not modifiable. The best you could do is hook into the CheckSpawn event on the forge event bus and make sure the entity is not on the world's surface or below a certain y value.

Please post the random words from the console in a gist or pastbin and link it, thanks.

It's currently supported on 1.19, so I'm not sure what you are talking about.

This suggests that there is probably a client only mod on your server. So you might want to remove it if you happen to know what it is. If not, you can post a mod list and someone will probably figure it out.

The Attributes class? Again, I have no idea what you're trying to do here when you're talking about json files.

As I said, probably some or all of the mods erroring most likely perform concurrent access on things. Typically, they can work without issue or crash sometimes; other times they always conflict. You might want to make a list of mods you added and then do it once again one at a time to see which ones are actually conflicting.

Well, it says check the console for possible error messages, so you could try enabling that (no idea how, search on the internet), and post the output here. It may have the solution.
