1) My spy just noticed that some of the Yuezhi's units seem to have an upkeep cost of zero. I noticed this specifically on Subeshi Archers, as well as the general's unit.

2) The Yuezhi's general-unit is a "Pontic General".

3) On the campaign map, there's a "land-bridge" where units can walk one or two squares over water in the Sind province in India, where the sea cuts into the land mass. Incidentally, the coastline doesn't look "clean" here.

4) The Baktrian pre-battle speech uses the vanilla Roman models.

Sorry if any of these have been brought up before. I'll be back with more if I find anything. Great mod, by the way. Excellent work ;)
