Pleae keep this forum in english. So since I can't read your original post anymore, I'm guessing it's the "Colori:" entry on the tooltip you're asking about. My best guess would be JEI doing it, if you remove JEI to test, is it still there?

This happened to me when I created json files from the commandline, it created an invisible character at the beginning for some reason. Rename your file, create a new one within your IDE with the original name, and copy/paste your json into it, and it should work.

Can you be more specific? Maybe a screenshot? Not totaly sure what you mean, and I haven't heard of anything described like that.

Have you made any other recipes (in this same mod workspace) that work? Just wondering if your package name/folders are good, I've been seeing a lot of broken package names lately, i.e. package data.modid.recipes which should be resources/data/modid/recipes, I've seen it end up being resources/data.modid.recipes instead. Your json looks right as far as I can tell, and if the items were missing/not registered, pretty sure it would throw errors in the log.

Really really really old versions of Minecraft/Forge are no longer supported. Please update to a modern (1.14.4/1.15.2) version to receive support. More information on supported versions can be found in the LTS link at the top of every page.

Also any particular reason you're running in offline mode?

Just for the record, I never said that, you shouldn't quote things people didn't actually post/say. Judging by the filenames of your mods, you downloaded them from 9 mine craft or some other Bad Website. These mods are illegally hosted/distributed, and can be outdated, incorrectly labeled, or even tampered with to including malware. See https://stopmodreposts.org/ for more information on what sites to avoid. I personally will only download mods from Curseforge or the mod authors website. I would go and delete all the mods you downloaded, and redownload them from curseforge.com. If a mod is not available there, and only on a shifty website, I would skip it to be honest. Safest way to go. Also, side note, don't put Optifine on a server, it's a client/graphics mod.

Unplug G-Shark GS-GP702 and see if that helps.

Ah, 1.12 is no longer supported because it's old. Only modern (1.14.4/1.15.2) versions are supported. The LTS link at the top of every page has details on supported versions.

Which version of forge/optifine? Also posting your debug.log may help reveal the cause

You should be able to play the modpack using the vanilla launcher with the method I described. I would just use twitch for downloading them, and then setup the custom profiles/launch them from the vanilla launcher to avoid twitch-caused installation issues with forge. The Twitch launcher seems like it's always screwed up with new versions (at least I see lots of forums posts about it), they don't know what they're doing when it comes to installing forge or something.

Are you running this through the twitch launcher? If so, I would download/install the latest forge from files.minecraftforge.net, then create a new installation in the vanilla launcher using that version and specifying D:\Spiele\Twitch\Minecraft\Instances\Modpack as the game directory, and see if that makes a difference. Twitch launcher is great for getting mods/modpacks, but really it's garbage.

Hmm, can you post the debug.log from a run when this happens?

I've found that some things don't work quite right with DeferredRegister, and moving it over to a proper registry event makes it work. Just for grins have you tried that? Also, you should post the whole project as a github repo, makes it much easier to see the big picture. Also please post the debug.log. More info == better!!

Please post the debug.log from the server.

Not everything has been mapped yet, so you either have to wait until someone does, or figure out and submit it yourself to MCPBot (or something like that, I haven't really done any messing with that stuff yet, I just use what they gimme ) http://export.mcpbot.bspk.rs/ has the latest/stable mappings. I just use the (close to) latest one, has more stuff mapped, and someone said somewhere that the snapshot ones don't get broken very often so it's relatively safe to do. If you're not using 1.15.2, I'm not sure if using the 1.15.1 mappings is bad or not for 1.14.x (or if it even works). I just do everything in the latest version myself.

Edit your build.gradle find this line: I usually change the version to whatever yesterday was. Then refresh your project, and it should redo everything for ya.

There's nothing stopping you from doing so, however if you have problems you won't be able to ask for help here. For old versions you could try the official minecraft forums, I know they have a modded section over there, I just don't know what it's like, as I don't go there. There are tons of good mods for current versions, it might be time to let go of old outdated mods that have been abandoned and don't get updated to current versions!

You should really create your own post instead of digging up a post from a year and a half ago. That being said, 1.12 is no longer supported due to age. To receive support, you will need to update to a modern (1.14.4/1.15.2) version. See the LTS link at the top of every page for more information on supported versions.

Please keep this forum in english. Please post the debug.log from the logs folder.

Which version is this for? If it is lower than 1.14.4, you will need to update to receive support. Otherwise, please post the debug.log (located in the logs folder in the minecraft game directory), and also maybe a screenshot of your mods folder, including the full address bar at the top. That should give enough information to get started figuring out what's going on.

Please post your debug.log file. Also, make sure you read up on all the mods you install, it's possible one of them requires another mod/library that you did not install.

The .jar installer will do it for you. Make sure you have 64-bit Java 8 installed. If it still doesn't work, post as much detail as you can on what you did, and what did/did not happen.

You need to add your feature to the biome you want, look in net.minecraft.world.biome.DefaultBiomeFeatures for examples You would do this in FMLCommmonSetupEvent, within a DeferredWorkQueue (the javadocs for it show how to use it)
