Some stuff from German forum

" Failed to find Texture´data/models_unit/Textures/Kalis_Unit_Sarmation_Spear.TGA"

This Message was received by somebody upon his ctd, maybe this is something new.
Also he reported that his ctds mostly occured when the seleucids used spys (or directly after that), he could see that as he was playing epeiros.

And he said that our siege graphic blocks armies from being put near enough to enemy cities to support the assault.

And he reported quite a lot of stuff we definitely already know (animation bugs, etc.)

Well failing to find a texture is a likely result from a bad install. I remember reading somewhere on here about a buggy spy death animation, I don't know/remember if it caused CTDs though.
