Some issue with a missing class for a mixin. Which usually means you are missing a mod required by another mod. iris? diebuddies? There isn't much context in the error. The log does show: But that looks to be a completely different error where you have the wrong version installed.

You need to show the logs/debug.log for the server so we can see the error.

If that really is the full logs/debug.log post the launcher_log.txt

There is no error, but the last thing in the log is it trying to read the fml.toml file. Likely the file is corrupted. Try deleting it and it should be recreated with default values. Otherwise post the launcher_log.txt to see if that shows an error.

You can't have both jei and rei.

You have some issue with it not being able to resource packs. The error message does not give any other context. Maybe the debug.log has more information?

There is no jar for modern minecraft hasn't been for a long time. You use the scripts.

minecraft:pig is minecraft's way of saying "entity not found". You have a mod that is not registering its entities properly. Myabe the debug.log has more information about which mod it is because that crash report does not say?

Some issue with the the abyss mod's key mappings. Check you have the latest version then contact the mod author.

You have lots of mods trying to load client classes on the server. Assuming these are just client side only mods written by lazy/incompetent developers you can remove them from the server.

You have this problem: https://misode.github.io/guides/feature-order-cycle/ It is caused by mods conflicting in their worldgen configuration. One of the mods is byg (oh the biomes you will go), mentioned in the error. Unfortunately, Mojangs error doesn't show the other mod. Contact the byg mod authors, maybe they can help you? Otherwise you will need to experiment with removing mods until the problem goes away to find the other mod. Backup your world(s) before removing mods.

You have a mod trying to load client classes on the server. Maybe it is one of those client side only mods that doesn't work on the server?

The time is in ticks. 20 ticks per second. The vanilla values can be found in AbstractFurnaceBlockEntity.getFuel() Coal/Charcoal are 1600 Or you could call ForgeHooks.getBurnTime(Items.COAL.getDefaultInstance()); if you don't want to hard code it.

If you are writing a mod then you should use GLMs to modify the loot tables (so you play nicely with other mods trying to do the same thing). https://forge.gemwire.uk/wiki/Dynamic_Loot_Modification Otherwise, you can do it the vanilla way with a datapack by providing your own zombie loot table(s) https://minecraft.fandom.com/wiki/Loot_table Extractions of the vanilla entity drop loot tables can be found here: https://github.com/misode/mcmeta/tree/data/data/minecraft/loot_tables/entities Or you can use one of the scripting mods, e.g. https://mods.latvian.dev/books/kubejs-legacy/page/loot-table-modification https://docs.blamejared.com/1.19/en/vanilla/api/loot/table/LootTableManager

override this method for your item: https://github.com/MinecraftForge/MinecraftForge/blob/f03adc840e031b0c772e07ddda4ab910e367469a/src/main/java/net/minecraftforge/common/extensions/IForgeItem.java#L687

Nope: https://www.curseforge.com/minecraft/mc-mods/geckolib/files/4407092 You the have the 1.19 version (the 1.19.3 part is you trying to use the mappings from 1.19.3 with 1.19 which isn't going to work well).

Sounds like you have the wrong version of Geckolib for your version of minecraft. Those com.mojang.math classes no longer exist in recent versions of minecraft. But you would be better off contacting the Geckolib developers with questions about their mod.

Use java 17, mixin does not support java 19

Issue with the untamed wilds mod. Check you have the latest version then contact the mod author.

Lost cities does not say it has a version compatible with 1.19.4 (Mojang completely changed the create new world screen in 1.19.4) https://www.curseforge.com/minecraft/mc-mods/the-lost-cities/files Contact the mod author. But I would guess you need to wait for them to release an update?

Use java 17, mixin does not support java 19

This isn't the kind of thing you will normally get help with in this forum. This falls under the bots/cheats category of mods. But if you want to find the modern mojang method/class names for older pre 1.17 forge names, I believe there is a bot on the forge discord you can use? https://gist.github.com/50ap5ud5/beebcf056cbdd3c922cc8993689428f4#migration-of-method-and-field-names-to-mojang-mappings

You can also ask the biomesoplenty developers or search their bug reports to see if the conflicting is already known for sunflower_plains.
