Orc Army crash

I'm playing Wissenland and I have a full stack lead by my Heir in Averland. I won a hard battle last night heavily out numbered, so I got pretty good at beating Orcs. Today 2 stacks attacked Averheim with only half a stack in Averheim. So here I come to the rescue problem is it CTD loading the battle. After multiple reloads it still crashed. So screw i didn't want my save to become corrupt like my Middenland one. The mad count of Averland came to the rescue owning the Orcs and even I was surprised. 5 turns latter my prince attacked a lonely stack of Orcs while the ratio was in the Orcs favour I still liked my chances of winning.

Guess what it crashed, but not all battles crash just fighting the Orcs it crashes. The log doesn't say much just some missing textures and overlay textures which all battles have. My theory is that its the units with the siege weapons that got created. BTW to the dev team you should never create a unit with siege weapons, creating units is bad enough if you do it correctly but that is no where near correct
