Dwarven Miners for elves will not drop off at treant, and wonder around aimlessly. I saw post from July saying it was going to be fixed on the next patch, which obviously never happened. I tried to go to a human a city for a horse-cart...that was just a waste of money for a beginner. Cost me 1000 gold to walk there and back. Diplomacy would of cost 1500 gold which I didn't have. Also add what-ever a horse-cart cost. Its pretty sad that a bug reported 6 months ago is still broken and work-around would cost you a couple thousand gold.
The cost for just your hero to walk on the map is pretty outrageous in its self, like I said I wasted a 1000 gold to make a pointless walk.
Please don't post your fixing something and leave it broken 6 months later! It would be nice if you added a note to market saying that Miners don't work for elves.
