I have been playing MLBS for quite a while now, but have seemed to run into a ore vien bug. When I start up a new game and go to mine some ore, I only find that all the ores are stone, no valuable materials. 

I have tried waiting a couple days to see if they reset, but still nothing.  I have also tried reinstalling the game, even a different bit size, but still nothing. It's really hard to play this game when you cant mine ore, so any help would be appreciated. 

Sorry for the long winded message, and thanks to those who help.
