So, today, (7/7/2016) I was messing around with the Kitchen Mod, and I searched "sandwich" in the NEI GUI (*laughs*) and I saw a, well, sandwich. Except when I put my cursor on the sandwich, it didn't show a list of it's contents. First I thought, Um... what is this? Then I realized: It didn't have anything in it. So then, I did what anyone would do: I took one so I could eat it. But, the second I clicked it, the game crashed because I had a blank sandwich in my inventory. So, I tried to go back into the world, and It crashed again because it was still in my inventory. I corrupted ANOTHER world!
