I successfully made a 'WORKING!' 3x3 hammer, but same procedure doesn't work anymore... I had the hammer working to mine a 3x3 area depending on what direction you were facing. North, east, south, and west were all working. I had to do something special for south because it goes across the 0 mark, minecraft uses necatives, but MCreator doesn't(Which is why I had to do something special). It took me around an hour to do. It didn't work for a long time, then I decided to rebuild everything exactly how I originally had it. It finally worked, but I saved everything and closed MCreator, opened it a couple of days later, and it no longer works.. I made no changes to the script that made South work, I just added east and west. Then it stopped working...

Why does it do this? Is there a simple solution?

EDIT:

It works now... But I'm sure it'll keep doing that, I could give you(MCreator team) my procedure if you'd like to further test it yourself.

EDIT:

It doesn't work again... Except this time, none of the directions work, I didn't even stop and start minecraft it just kinda stopped.  <o>

EDIT:

Now I'm getting really mad, it is now not building the workspace completely because apparently there's an error in it...
