Yes, they are designed to be used in datapacks. But the global loot modifiers are a bit subtle. They are additive by default, like tags. So it will run both the mod's and your loot modifier. If you don't want this, you need a data/forge/loot_modifiers/global_loot_modifiers.json and use the "replace" option to stop the mod's loot modifier from being run. That's not something I have ever done, so I don't have an example. See: https://forge.gemwire.uk/wiki/Dynamic_Loot_Modification#The_global_loot_modifiers.json for more details.

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

Conflict between apotheosis and unique enchantments. Check you have the latest versions then contact the mod authors.

It's a known issue: https://github.com/MinecraftForge/MinecraftForge/issues/9412

Looks like a conflict between rubidium (a fork of sodium) and chunkanimator. Check you have the latest versions then contact the mod authors.

I just tried this with the older 45.0.9 and get the same bug. Player's can't pick up other player's thrown items. What's weird is when the player that threw the item leaves the game, the other player can pick up the item. So this must have something to do with the hidden thrower/owner field in the ItemEntity? I reported it here: https://github.com/MinecraftForge/MinecraftForge/issues/9412 and XFactD said it was a known issue: https://github.com/MinecraftForge/MinecraftForge/pull/9404

Issue the carpet mod. Check you have the latest version then contact the mod author.

Issue with the valhelsia_structures mod. Check you have the latest version then contact the mod authors. But others have said in the past that the valhelsia mods are not compatible with optifine.

The actual error is with the curios mod screen. But it could also be caused by whatever is providing that zpf000$onRender mixin. Unfortunately, the mod author didn't give the mixin a name that identifies which mod it is. Candidates are the ones I have underlined, i.e. balm, ae2, mousetweaks, smoothswapping and ipnext Check you have the latest version of these mods and then contact the mod authors.

Issue with bookshelf mod. Check you have the latest version the contact the mod author.

We need to see the error in the logs/debug.log

Editing the question to the remove the reference to "autonomous agents" doesn't change the fact that the information requested is mostly used to write bots. Anyway, here's a dicussion of why what are asking is pretty much impossible in general for modern minecraft: https://forums.minecraftforge.net/topic/118158-1182-getting-ore-rarities/#comment-519809

Check you have the latest version then contact the mod author.

Cheats/bots are not supported in this forum.

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

It's long because that property makes mojang's code log all the debug information. You can turn off that debug now, by removing the property. The problem is with immersive portals. Check you have the latest version then contact the mod author.

logs/debug.log You should check it contains that NullPointerException error message before posting it to make sure you have set that property correctly.

It's not clear what you mean by "minecrafts structure_block" but I guess what you are referring to/looking for is? StructureTemplate.Palette.save(CompoundTag) That has code to put a ListTag in the compound tag, see newIntegerList()

You can't have uppercase characters or spaces in ResourceLocations. That includes file names in your mod's resource/data packs.

Remove optifine and confirm you don't get the same error. Forge by itself doesn't have this error.

You are not the first to report this issue with multicraft and BetterMC All I can tell you is that one of the mods is hard crashing the game with a broken mixin. There is no other information in the error information, it doesn't say which mod. You need to speak to the BetterMC modpack developers or multicraft. If you find out what the real problem is, please report it back here for others.

Don't you have your own DeferredRegister that contains your items? public static final DeferredRegister<Item> MY_ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, MODID); then for (RegistryObject<Item> itemRegistration : MY_ITEMS.getEntries()) { var item = itemRegistration.get(); // do stuff } You also have the issue that you are adding every item to every tab. You need to check: event.getTab() is the tab you want.

If the mod is not called fabrication or maybe c_tweaks. I don't know. The mod author hasn't named their mixin file in a standard way so we don't know which mod it is. You could use a zip program to look inside each mod jar and see which has a "fabrication.mixins.json" file.

Path worldSaveDirectory = minecraftServer.getWorldPath(LevelResource.ROOT); Should get you the current save?
