Why can't I gather resources other than basic ones? They shows as question marks and are unable to gather. Do I need to do something to unlock them?
I'm sure it apply to Iron Wood and Magic Wood since I left them in dungeon to gather later but I can't appoint workers to them. And on the map they shows as question marks.
Something like this:
Location with unknown resources (Magic wood and Iron wood i guess)
Working tab where those resources don't show at the same location
