Yep, same error:

"factorio test integration has unexpected content"

I also noticed the update created a new "tests" directory in the program files directory, not the Factorio directory

Big crash here. I was driving the tank through a set of four gates when I got this error. All sprites disappeared and memory leaked to use all system memory! I really like the new features aside from this! :D http://i.imgur.com/flXchxH.jpg Non-cropped screenshot here http://i.imgur.com/flXchxH.jpg
