So I'm playing the Yogscast Complete Modpack on the ATLauncher, and one of my worlds is...well, I'm not quite sure how to describe it. When I try to load up the world, it gets stuck at loading Dimension 1. It doesn't crash, it just...stops. If anyone can tell me what the heck is going on, I'd be their friend forever. I don't need you to fix it, I've pretty much given up on this world...I just want to know what happened. I'm going to try deleting the data files for Dimension 1 after making this post and see if that helps, but I'm not hopeful.
Below is a dump of the launcher console; it contains everything that happened between initiating world load and the freeze.

Edit: this also happened before removing ChickenChunks and JABBA. It was getting stuck on something from JABBA, so I removed it, and I removed ChickenChunks because...well, it was worth a try, right?
Below is a dump of the launcher console; it contains everything that happened between initiating world load and the freeze.

1. Re-Add Chicken Chunks
or
2. Update ChickenChunks by disabling the mod, then download the latest version of the mod for 1.6.4 on this thread (http://www.minecraftforum.net/topic/909223-164-smp-chickenbones-mods/) then adding and enabling that on the modpack.
or
3.Contact the support people on the ATLauncher website and see what they suggest or if they have seen other similar reports.
I hope this information was helpful and useful to you.
