Modpack Crash issue

[cluedo97]

Hey I know this is not a FTB pack but the atl launcher community is horrible and I hope someone can look into this crash log and see if something is wrong.

I am using Overload from ATL launcher and I have optifine, allsnow and bettersnow mod installed but I get the same thing without these mods.

so here is some of the crash log I also have the whole crash log here http://pastebin.com/CB2jV9dF

Don't blame ATLauncher. They support issues with the launcher. The individual packs offer support for their mod mix. Overload has their own support forum and the link is in the ATLauncher forums. http://www.dslacky.com/

I've provided the link since you probably didn't look at the ATLauncher forums before bashing them. Hopefully the actual supporters of your chosen modpack can help you.

I don't blame ATL launcher but if you look at their forums like overload many of the threads their haven't even been viewed by people

I have the same problem with a ftb custom modpack
Could you help me?

 

[cluedo97]

for me it was optifine that did this

Modded Minecraft Tech Support groups (FTB Tech Support, ATL support, Technic support, etc) will generally not provide any support for people that add Optifine, or any other mods to their modpack. They are designed to work as is, not with added mods. Mods like FPS+ and Optifine do base Minecraft class edits that can cause a lot of graphical, and even just crashing problems.

The problem is from the mod chicken chunks; we can see it in the log
I tested without it and it worked
(PS: sorry for my english, i'm french)
