Can you post your code to GitHub so I can test it on my end?

You're using an ancient version of Forge for 1.12.2 and trying to load a (presumed)1.7.10 coremod.

Decocraft2 requires PTRLib and this has not been indicated properly inside the mod so Forge doesn't catch it with a Missing Mod screen. I have been told that the next release of Decocraft2 will fix this issue, however.

If you do not have Optifine installed please provide your debug.log as described in my signature below.

Could you post the code to a github repo? It's easier than us asking for each individual file.

A lot of tutorials are crap and/or horrendously outdated.

General Issues #1

Please don't necro. If you have a question please make your own thread.

You want to make sure you have the same mods and the same configs on both computers.

1.7.10 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

A common theme I see among fans of old versions is the tendency to push that their favorite version is the "best" version and that their opinion is somehow factually proven, rather than their opinion.

I'm not sure I understand this issue in its entirety, from the code I'm looking at 0b without quotes should get you 0 as a byte, yes this messes up syntax highlighting and Json verification as it's not 100% pure Json, but from what I'm seeing that should be what works.

Yes, that version fixed an issue with the server's GUI

Make sure your command to start the server includes the forge file's .jar extension, also you appear to be missing the -universal part of the filename if that was a direct copy-paste.

If the server is generating a debug.log please post that as described in my signature below. If you are referring to the text box being blank, try a version after 14.23.4.2749

User was banned for using a cracked launcher. Buy the game.

Aside from using Java 9 when Forge for 1.12.2 and below requires Java 8... This is an error coming from the JVM, not Minecraft or Forge.

To my newbie eyes it looks like a RefinedStorage block somehow has a Wizardry TileEntity attached to it, can someone with more experience confirm?

This sounds like trying to fix a symptom rather than the cause. Can you provide logs from the server(and possibly client) that show this happening? Please refer to my signature for which log and how to post.

I think I remember hearing something about a bug involving Optifine and chests, for the life of me I can't remember where though.

If you have a 1.12.2 folder in your mods folder look in there, some mods extract a component into that folder and it runs on its own, which then crashes if it can't find the rest of the mod.

Please post logs as described in my signature, I don't think Forge is to blame.

By default your mods folder is in .minecraft
