Sorry dg. You were so close at the end there. Just need to place the forester early so you can cut/plant trees and the rock comes from the mine. there are a few little caves scattered around that you place a mine on and they start harvesting it at that point. Thanks for the playthrough!
No worries. I assume it was calculating screen space based on the defined screen size and not the actual screen size. Should be a quick fix if you want to make the fix! Fixing bugs is allowed.
