My seemingly small 155mb patch turned into a complete re-download for Warhammer 2. Yes, I know this is not CA's problem and more of a Steam problem but this has happened about 4 times now but only for this game. And to make matters worse, my peak download speed is only 3.8mbps... It's the "best" available option in my area. It may just be completely coincidental, but this has only happened for my Total War games and no others.
