Minecraft Forums

So I started a new world, and have been exploring around a bit. Recently I had a spot where the world sort of hung up without crashing, and I had to force Minecraft to close. Unfortunately, I didn't have the presence of mind to save that crash report. However, ever since that moment, when I load up Minecraft again, the world comes up, everything starts to load, and then BAM. Crash. So this world appears to be unusable now, unless it mysteriously stops doing this on its own.

Here's the crash report. Any help you guys can offer is appreciated. Right now it's looking like I'll have to start removing mods, but I've already put a fair amount of work in. If I have to start removing mods, I'll be losing all that research and crafting.

Thanks!

Hm...I'm reasonably sure they're all 1.7.10. I've been using most of these mods for quite some time now without seeing this happen.

That said, I'll go over them with a fine-toothed comb and make sure none of the new ones fit that description.

Thanks for the input!
