Diorite Isn't Useless

0.3.1-beta (Bugfix)

Fixed:

• The Miner could give you coordinates to an abandoned mine with no way in (the shaft ended up under a river or lake, so you just found water). Now mines only generate if the shaft can actually reach the surface.

Heads up:

• Mines generated in 0.3.0-beta worlds are still there, but the Miner won't point you to the ones without a shaft.
• Mines may be a bit rarer near rivers, lakes and coasts.
• For the fix to apply, explore new chunks or make a new world.
