thanks for making great game even better!

Since I bought Factorio almost one year ago it is still my favorite game that I play. What amazes me is that new content is still beeing provided even that game in current shape is better than many AAA titles. Great job!

I was updating Factorio using auto-updater from 13.20 to 14.21. It started and finished download. Then the updater started and crashed.
I'm attaching log files.
Game won't start anymore.
