I noticed that when ever I put Anything, into a furnace that I don't get exp from removing it.
I've tried taking it out and placing the items into my hotbar, or my inventory. Neither works.
Hello? Um just wondering if this is either a glitch, or something that was missing from the game from the start?
I DO, get exp from killing things, and from collecting Ore from Redstone, Diamonds, Coal, and Lapis, haven't encountered Emeralds yet..
Maybe you are just smelting very little food. Meat like beef and chicken give you only 0.35 exp as Gold ore gives you 1 exp.
