Sorry if this has been posted somewhere else but I couldn't find it. I recently updated to 1.0X.010 and noticed that the Movies folder is now empty (but still shows up as Installed) and some of tutorials thumbnails are deleted and ALL the tutorial movies. I've also noticed that all the mini-tech movies are gone too. Argh.

I restored an archived version of the game (1.D1.008 I think) and the movies and tutorial thumbnails were restored. Updated again and the movies/thumbnails were once again gone.

Is this a bug with the updater?
