I break blocks, but can notpick them up
I'm mining, I look in my inventory, but not a single block has been picked up. I'm in survival mode, mining stone with a iron pickaxe. Shouldn't I get cobblestone?
As Unionhawk and aytimothy said, if you have cheats on, then type in /gamerule doTileDrops true.
You either have the gamerule set to "False" or have mods installed.
