Hello everyone.

I have a problem and I hope you can help me fixing it. I can not place the mining operation in Single player. I have large areas without anything at the ground and they are plan as possible - and I see allways there is not enough contact to the ground or that something is in the way. Which both doesn't is true.

Is there something that I have to look at to place the buildings ? At a point where the ressource are naturally for example ? I don't know where the problem is. Please help.
