[3c][Bug/Gameplay] Warg mount incorrectly requires horse resource.
When adding a warg mount to a unit in the unit designer it indicates that it requires a horse resource to make. This should probably be a warg resource. With 25 warg resources I was not able to buy a warg enabled unit. So it does indeed appear to require a horse unit. From what I can tell playing empire there are no horse tiles that I have found.
