Using forge .1231, a custom modpack, and doggy talents v1.8.3a. I was typing in the name for the new world I was going to generate, and I suddenly crashed.

This is what I got: http://pastebin.com/JMUcNDNR

Until this is fixed, I will be reverting to doggy talents v1.8.2a. Please take a look at this whenever you can, thank you.

I can confirm this and that it ONLY happens when pressing the spacebar, beyond that we seem to be having no issues with the mod (though we have yet to do through testing)
