Minecraft Forums

I'm no Minecraft expert by any means! I recently downloaded Traincraft, the latest version, and it's been working fine. I use Forge, have my proper loaders, and everything seemed to work fine.

However, my world will crash whenever I open it up now! Everything was fine a a few hours ago, but I can't figure out what changed in that time. I've restarted my computer, and even tried a new world, but nothing seems to help.

Any advice would be greatly appreciated! Thank you
