If anyone can help, that would be great! I Have never experienced this error before, and I hope the problem isn't BF, but that might be the problem. I've looked around at other threads, but all of them in the end say something about NEI being the problem. I do not have NEI downloaded.

I did not specify a few things.

Thanks for the help! I'll do that.

Edit: I downloaded the extension, just to make future mod-finding easier. I'm currently downloading the actual files from CurseForge, and transferring them in.

It seems faulty files were the problem! Everything seems to be working right now. The actual files for Mo'Creatures' addon that is required for mobs spawning in the world, Custom Mod Spawner, dooes not have a 1.12.2 update. I could not find an official file for it. I found a different mod that I hope works, but I'm really missing Mo'Creatures. Thank you for your help.
