When mining on smp6, I've noticed that I'm not receiving all of the materials. Once a block is destroyed (i.e. cobblestone) the blocks disappear therefore I'm unable to collect the materials. It's like every fourth block that I destroy is when I'm able to collect the materials. Also, when mining redstone, I used to get 4 redstone per block and now I'm receiving only one.Has any of you experienced this or is it just me?
