I am putting together a completely private modpack for my own enjoyment, however, every time I create a world I get that crash error and when I relaunch minecraft, I find out it didn't create the world. I have googled extensively for solutions and I am lost. Any and all help will be appreciated.

There is a full mod list in the crash report

[Edit]: Fixed typos

Thanks heaps, I'll try that now.

Edit:

Thanks, that worked, I rolled back about 10 builds and now it works fine.

Edit 2:

It crashed upon finishing loading the world but that was caused by optifine not getting along with forestry and mantle.
