While crashhunting I ran into this little oddity. I'm not sure if that's the one that crashes, but it's still odd.

In this Seleucid fort an entire Pahlavan army is hiding in one unit slot (clicking on the banner reveals 3 cavalry units) as well as the Seleucid unit. Could this be the reason for the ctd and if so, what if anything can be done about it?
