My old fort crashed while saving (forget YOU WINDOWS 7, YEAH, IT'S PROBABLY CAUSING IT TO CRASH) and it corrupted the save file or some stuff.
I've generated a new world because for some weird ass reason I cant reused world 3 (my really large world that took atleast 2 and a half hours to generate) and this world IS LOADED WITH hematite, limonite, and magnetite. I've hit coal too, and plenty of gems.
I've already also hit a metric asston of native gold. I've got slate and gabbro on this level so I'm bound to hit platinum soon while mining, and I plan on digging down and getting into the magma seas to immediately so I can begind making iron and gold for trading/weapons.
Also unlike my older save, I've actually hit the underground caverns this time so I'll have to make another central staircase to go around it down to the magma seas.
ninja edit:
AAHAHHA, FIVE SECONDS AFTER POSTING THIS I HIT PLATINUM
woo.
