So the problem is is that if you mine the stone too quickly it will eventually do this:
[media]
the game thinks that the water has no where to go and so the lava goes down and the game doesn't realize there's water there. This causes lava to be where the stone would be generating, and that will cause the stone generator to stop working entirely or just produce cobblestone (depending on how laggy your game is) I hope this helped the devs/coders/etc. understand so they can get this issue taken care of.
