What version of Forge are you using?

There's a problem with some mod's custom model handling returning null where it shouldn't. You can try splitting the remaining modlist to find which mod is causing it, so it can be reported to the author. Otherwise, if this PR is merged, you should be able to see the offending mod in the log output. For playing the game in the meantime, you can use Forge build 2575.

Leave changes to the json files, they happen due to Mojang tweaking libraries/assets. As for existing patches changing, it's because those files were previously changed without the patches being regenerated properly. As a result, running genPatches creates patch files that differ from the originals. Just commit the files/patches that correspond to what you've changed.

Seems like this is an issue with JEI.

Java 9 isn't supported currently, you need to use Java 8 for now.

The Forge blockstate format is specified here: https://gist.github.com/RainWarrior/0618131f51b8d37b80a6 Also, from looking at the vanilla wiki: https://minecraft.gamepedia.com/Model#Block_models, you can 'offset' the rotation of model elements in 22.5 degree increments.

Can you see if a Forge client can connect if you pass -Djava.net.preferIPv4Stack=false as a launch argument (to the client)?

There's a PR for this issue open here: https://github.com/MinecraftForge/MinecraftForge/pull/4547

1.12 updated the version of various libraries, including Netty (4.0.23 -> 4.1.9). This would seem to be the culprit: https://github.com/netty/netty/issues/5657 I can't find a call setting "java.net.preferIPv4Stack" in Main.main, and the FML code dates back to July 2014 (https://github.com/MinecraftForge/FML/commit/ab52901b8b47a525e2719cf280327e97bad7f91e) so it's probably no longer needed.

This should be fixed, can you try build 2548+ and see if hosting a LAN world with that version works correctly?

Does this happen every time? Is this a plain Forge server, or with mods installed? If there are mods, does it still happen with just Forge?

Your getStateFromMeta and getMetaFromState methods don't match.

Try the alternate download links (click the "i" icon next to the main link).

Do not upload the decompiled Minecraft sources, with or without Forge patches applied, to the Internet. If you want version tracking for these files, then use whatever features your IDE of choice supports, or host a git/whatever repo on your local machine only.

Most likely you have an older version of Guava being used here somehow. Check the listed libraries, Minecraft 1.12 uses Guava 21.

Java 9 is not currently supported, use Java 8 for the time being.

Assuming you meant 14.22.1.2479, try using build 2485+. There was a bug that could possibly be affecting this.

What version of Forge are you using?

For worldgen, you should probably pass the flag 18 (16 | 2). Otherwise the game will trigger updates for observers, which will also load chunks. In this case, vanilla isn't the best example to follow, as Mojang didn't update the flags they used for worldgen when that new flag was added.

You're missing a required mod, or something isn't the right version. If you read through the fml-client-latest.log file, it'll say what's missing.

You need to override getBlockLayer() to return something other than SOLID. CUTOUT is probably what you want here.
