Details of the issue:

I was trying to melt down unstable nuggets in order to make an unbreakable pickaxe and, to begin with it was acting up with bad numbers, ie: I had 2 ingots worth and all of it went into a pickaxe head instead of half of it, and I stepped away from my computer- when I came back, the game had frozen completely and would not respond after waiting an acceptable amount of time, so I ended the game process and when I restarted the game, it simply would not and will not open my world. It's only that world, as my creative world is fine.
Any help is greatly appreciated, I can post more logs related to the specific world crash if needed​
