Hi... I loved your idea. I installed your mod. BTW, this is the very first, and only mod I have, so far, actually, installed. Played the game. The new 'building' did appear. I built them. They showed "horses produced: 0" I did have a wild horse tile improved, as well. I was able to train mounted units.
Questions, please: do the stables produce horses even if the message says "0?"
Perhaps I installed the mod incorrectly? I put it in the mods folder, and set it up with the same folder structure that was in the zip. Is this correct install for ver 1.09? Thanks, keep up the good work!
