I am making an adventure map and because the new update buttons can be placed on top of and beneath blocks, I am having issues. This is a problem because I only give pressure plates and redstone when it is needed for a certain door.
If they have a button and need a pressure plate to open the door, players need to search elsewhere, but because they can put a button where a pressure plate would be, they bypass everything. Is there a way to use a command block to prevent players from placing a button on the floor?
