my first dive into the world of  REDSTONE!!! if it does not work properly, try the later mentioned fixes. i put in the same seed and everything. if it doesnt work, sorry. if its a matter of coordinates, its at 737 5 634. if it doesnt show up all together, make sure that its a flat world, it has cheats enabled, structures dont generate, its in creative mode, and bonus chests are off. if these dont fix it, sorry. :|
