Yes, add 'achivement.<name>=<name>' to your lang file.. you know... like you're supposed to.

What launcher are you using...

net.minecraft.client.renderer.StitcherException: Unable to fit: minecraft:blocks/lava_flow - size: 32x32 - Maybe try a lowerresolution resourcepack? Means you're trying to stitch together more textures then your video card allows. Either try a lower res resource pack, or remove some mods.

Its a Enumm... containing directions, and functions to manipulate them. It's just a abstraction away from minecraft's magic numbers.

Look how almost every item in vanilla minecraft does it... They all generate models based off textures...

Use the Forge installer. You DO NOT edit any jars or anything. Also, from that log it looks like your internet connection isnt working.

No clue, its NPEing inside CB's code not ours we cant do anything about it.

at codechicken.lib.world.WorldExtension.saveChunkData(WorldExtension.java:62) ~[WorldExtension.class:?] I wonder what mod could be causing it....

WARNING: coremods are present: Contact their authors BEFORE contacting forge

You changed gregtech you need a specific version. Place the correct version of gregtech in for your pack.

Try killing liteloader.

Thats not deprecated, those are missing, you need to call existing methods.

No, some mod you have installed has a broken command installed thats breaking all the others.

Exception java.lang.OutOfMemoryError I wonder what happened...

Define new music, we dont touch that system much. Minecraft just plays what the assets tell it to play.

Something on your end is blocking adfocus, you can just use the direct download links next to the normal downloads in the table.

Depending on what version of Forge you're using in the pack instance. If they are using a old version which doesn't have the enhanced loading screen then you won't have this issue. Hence why disabling the screen fixes it. It is a driver issue, from what we can gather it is a core driver freaking out thinking that it can render the desktop onto the item/block textures.

The Forge repo is going through a shift. We're trying to clean it up so it isnt two projects. But as is. the 'fml' folder can be treated exactly like the old FML repo. which includes the fact that you can use FG inside it to setup a workspace.

1) thats nowhere near the latest version 2) If you were on the latest version that would have a much friendlier error message telling you what the issue was.

What video driver do you have, some OSX drivers are broken, you can try disabling the splash screen in config/splash.properties it may help.

Some mod you have installed is trying to use mixins, Update that mod or remove it.

Interesting it doesnt say what is causing it but your crash is caused by a chest somewhere trying to continuously load itself/other chunks... Try removing any mods you have that deal with chests.

ChunkProviderServer.unloadAllChunks.. This appears to unload all the chunks... I wonder how it does that.. public void unloadAllChunks() { Iterator iterator = this.loadedChunks.iterator(); while (iterator.hasNext()) { Chunk chunk = (Chunk)iterator.next(); this.dropChunk(chunk.xPosition, chunk.zPosition); } } It loops through all loaded chunks.. can calls dropChunk.... But I only want to unload one chunk... I wonder what should I do?

0.o .... Wow this is ancient code. Not exactly sure where it came from as it's about 3 years old. It was probably mimicking some old vanilla behavior. Anyways https://github.com/MinecraftForge/MinecraftForge/commit/3331d2a496dcd69c0728539d740f6cf4bb46d98c should fix it in 1.8.

Run the jar from the command line and post the log. Also clear your internet cache and try downloading again. If you can get the MD5/SHA1 of the file you're running so I can compare it to the ones on the site.
