[MrFrostmaul]

Hello, I am making my own pack and it all loads fine etc.

But when I click on to create a new world this happens:

I have no clue why it is doing it

If anyone can help with this...

The deleting of the world was me manual but it the weird stuff after that when creating a world....

There is NO Crash Report..

Iam running the latest version of Forge and the pack is on 1.5.2
