I've built the Terracotta Army twice now, and both times it has given me far fewer units than it should have. I had 4 swordsmen and 2 scouts. It gave me 1 scout and 1 swordsman. The other time I had many composite bowmen and a few warriors, yet it gave me 3 units at most. There's plenty of unoccupied spaces around the city I built it in, so it's not that there isn't enough room. Can anyone tell me what's going on here?
