steam screen shot lock up

[PolePosition]

I was viewing my game with the map and zoomed in so i could get a screenshot of my train when i clicked F12 for the steam screenshot the game froze. it was listed as not responding in the task bar for about five min. i let it work and it eventually made the screenshot sound and continued like normal.

Thanks for the report.
I didn't manage to reproduce this, but I found out I left in my debug binding of F12 to entering a tutorial, so I removed it for 0.15.10 and hopefully that will solve this issue.
