So I'm playing as the romans and I conquered Carthage's capitol so it's trying to take it back. Well once it attacked me with Numidian Slingers (they could be the mercanary version if there is one since most of Carthage's troops were mercs). Well the graphical bug is that when I zoom out they dissapear as if they don't have sprites. Also the shadow beneath them is just a square.

*Edit* Nevermind found the solution
