Hey,
First off, great mod! I've really enjoyed it, I can't play Civ4 without now!
However, i've noticed that theres a couple bugs with the Byzantine units (My favourite BTS civ at the moment). Macemen animation is frozen, and you cannot promote them and assign advancement commants (disband, explore, fortify, etc.), I also noticed this for the Byzantine Chariot as well. Hopefully you can figure this out, as playing the Byzantines (which I certainly *must* do) is difficult without an Axemen counter or any warfare in the Middle-ages without Macemen.
