Hello,
I am attempting to make a modpack, and upon starting up the pack(from the default launcher). I get the same crash every time and I can't seem to fix it.
The crashes' "title" is: java.lang.NoClassDefFoundError: net/minecraft/block/BlockSlab and a full copy of the crash report can be found at this link: http://pastebin.com/X04J0x6e any and all help would be appreciated and more information can be given if necessary.
It looks like either Forge itself or one of the mods you have installed is built for a deobfuscated (development) client. Make sure you're not using development versions of mods.

Please don't PM me to ask for help or to join your mod development team. Asking your question in a public thread preserves it for people who are having the same problem in the future. I'm not interested in developing mods with people.
It looks like Extra Utilities is the first mod that wasn't Constructed when the game crashed. You could try removing that and see if it fixes the problem.
If that doesn't work, you can try using a binary search to find the culprit:
Disable/remove half of your mods and start the game
If it crashes, the problem is one of the loaded mods
If it doesn't crash, the problem is with one of the unloaded mods; so disable the loaded mods and enable the unloaded ones
Repeat steps 1-3 with the new set of mods until only one remains
Edit: Extra Utilities, not Factorization. I'm always confusing the two and I have no idea why.

I've done that, and it does appear that extra utilities cause that error, but now I have an entirely different error: java.lang.NoClassDefFoundError: io/netty/channel/ChannelHandler
