You don't happen to have two instances of Neotech installed do you?

No I do not

Honestly I'm not sure. There must be some other mod using that ID. We probably could have named the id more unique so I accept blame for the issue but on the same note someone else made the same lazy mistake we did. Try removing mods that contain chunk loaders and see if you are able to load without one of those

I believe I found the issue, the conflict is with a mod called "Chunkloader" and it is made by mark232
