i have a system where i have a redstone pulse that goes by every few seconds. it is connected to a command block that says "/testfor @a[r=6]". Then there is a comparator coming out of it that goes to another command block that says"/say Hello world and all who inhabit it." Even when right next to these command blocks, it still does not display the message like it previously did in the last snapshot.
