Ok to begin with i'm getting the following crashes at different stages of pack loading(normally around stage 2/3) with my one which is tweaked off the previous working build. The strange thing about it is that i can launch the pack by the other admin which has identical mod versions and it doesn't crash on me.

The order in which they were crashing seem to correspond to the mod loading order:

Draconic Evolution
Ender Storage
Immersive Engineering
Translocators
CodeChicken Lib

Any thoughts as to why my tweaked pack crashes and the other one with identical version isn't???
Cheers, The_Creamster.

I linked to the issue on the repo which was private(didn't realise that meant links to it appeared broken) due to the size of the initial post.

Did we ever find the root of this?

Closing due to this was outdated ccl issues.
