Samurai Cavalry and Yari Cavalry have two different models, on the battlefield, depending on how close you are to them. When you are zoomed out, the samurai and yari cavalry have flags on their backs like the normal foot samurai and yari samurai. When zooming in, the flags disappear. Again, like everything else I've submitted, this is not a big problem at all. --
This is related to the Ashigura's zoom/model problem. Upon closer inspection, it is not flags I'm seeing but the cavalrymen standing on their mounts. When zoomed in they switch to sitting.
Edit6: Apparently I'm seeing the 2d model standing and the 3d model correctly sitting. Same with the ashigura with this problem while dead: when zoomed in, the correct 3d laying model is used but the 2d standing model is used. I hope this helps. Edit7: Samurai Archer unit has this problem too; it will have a 2d standing animation when dead and a 3d laying animation when zoomed in. It is also half-invisible when zoomed out. (it looks really weird)
Yari Ashigura, in custom battles, do not have death animations when zoomed out...at least not when they've been shot by muskets. When zoomed out, the dead Ashigura are all standing in place rather than laying on the ground (Zombie Ashigura?), but when you zoom in...the close ashigura switch to the fallen position and then back to the standing when you zoom back out. This, more than any of the other problems stated, is detrimental as it creates, when zoomed out, what looks like highly disorganized units (tricking me into trying to click them and reform them, when there are actually only dead soldiers.)
