Unit texture bug

Hi there, new to these forums, searched for my issue but couldn't find it. So here it is... A few units have textures that won't work correctly, being the Dunaminica (and the units that look like it, as there are some in Eastern Europe i believe have a similar texture) and Iabarannta. The units are visible on the battle field but when zoomed out they disappear, leaving a square shadow and what look like feet (don't know what to call it, just white moving things where the soldiers should be). And when zoomed in the unit loads but with the square shadow. It's really annoying as it messes with the aesthetic look of the game and, as someone who has issues with ununifomrity, it kinda keeps me from using those units. Playing as the Romani on a HP Pavilion g series laptop with and i3 core on windows seven, if that helps. Thanks!

Edit: Dunaminica, Milites Ilergetum, Galathraikes, and Iabrannta, (Possibly) Gaesamica are the units affected by this bug.
