Lava generator doesn't work.

You can't make a lava generator. Wiem you make a hole 2x2 and lut lava on oposite corners, you can't take lava from other corners. Even im Nether, when you take a bucket od lava from "lava sea", you leave an unregeneretive "hole". I mean, you can't take a bucket of lava from this block again. This make lava a limiter resource.
