What you did was paste the bomb over the stone part, now, my bomb requires a small amount of empty space in the middle to allow the pcln to work, obviously, where there is no space in a stamp, what is behind the stamp replaces the empty space, ie: the stone. Now, what you need to do to make it work is erase 1 pixel of stone, yes, it really is that easy XD, If you look in the middle (with zoom) you will see 1 pixel of stone next to 1 pixel of pcln and the plut charge. Just erase the stone and it'll work again. sorry I didn't tell you this before.
