Install the applskin version that says it is compatible with 1.19.2 https://www.curseforge.com/minecraft/mc-mods/appleskin/files/all?filter-game-version=1738749986%3a73407

Looks like you have the wrong version of geckolib for the dreamland forge mod? Ask the mod author which version they want or try the latest version.

Install the latest optifine preview release for 1.18.2

One of the Level.getEntities() methods.

Your error is Which looks like some conflict between ars nouveau and geckolib. Like you have the networking code twice? You need to contact the mod author to ask what is going on. The image post is useless, we need to see the log.

Looks like an issue with Dynmap plugin? Check you have the latest version then contact the mod author. Also please stop posting logs in the forum. Upload them to a file sharing site and post a link. This thread is pretty much impossible to search and figure out which log I should be looking at.

You are missing the geckolib mod or have the wrong version.

You need to speak the valhelsia_core and optifine mod authors. I believe the answer you will get from valhelsia_core is "we don't support optfine". A stance many mod authors take since there is no way to know how it changes the game.

You are missing the smartbrainlib and modonmonicon mods or have the wrong versions for the mods that want them installed.

I believe the data it is complaining about is in the main level.dat file, but as I said I have never done this. You need an nbt editor to modify it, but you also need to know what you are doing otherwise you will break the whole save. If you do choose to modify it, back it up first!

The first log shows the client is losing its connection. I can't see the reason in that log. It's not due to initial connection timeout. e.g. in the last one it is 30 seconds after the player notionally joined the game. The second log seems to be an due to an error? Just before the player is disconnected they are getting a message about invalid data. For the first problem, you need somebody who can help you understand why that player is losing its network connection. It's not me 🙂 I would guess it is related to that player's computer struggling to keep up with running the game given how long it takes to make the initial connection (70 to 90 seconds)? The second problem looks to be a bug in a mod or maybe some mismatch in what the client has installed/configured versus the server. There are warnings from journey map at the same time about missing textures related to entities which might give a clue to which is the problem mod? I would suggest to start with getting that user to reinstall the modpack to make sure they have the right mods, versions, etc.

Issue with valhelsia_core. Others have said it conflicts with optifine.

I would backup them up first in case one of the mods is misusing the config file to store real data in someway.

If you have such a filesystem, the file size will be misleading. You could try something like wc -c * if you are using a un*x. It prints the "byte count" for every file in a directory. System admin commands are not really my expertise. 🙂

That's what I said above and why I quoted "empty" above. Some OSes allocate a certain amount of space for a file even if it is empty.

It depends how your OS reports file sizes. But probably, yes.

Look at the file sizes in the folder. If the OS failed to save the file it is usually "empty".

Oculus issue: https://github.com/Asek3/Oculus/issues/257

One of your mods has a broken/corrupted config file. You can find it world/serverconfig If you don't have a backup of this file, delete it and it will be recreated with default values. The usual cause of this problem, is your computer not shutting down properly (e.g. power outage) which means file changes are not flushed to the physical disk by the operating system. Forge updates the config files everytime you boot the game to make sure the files have all the latest config options specified by the mods.

There is no real error in that log. If it is the full log, post a link to the launcher_log.txt before restarting the launcher.

You should remove the broken client side only mods from the server. Or contact the modpack author or mod authors for help.
