Every time a steam achievement pops up, the game crashes. This just happened with both the "I need Trains" achievement and the "Assembly Line" achievement, and also happened with three achievements on April 28th. When I played immediately after 1.0 release (sometime before April 26th), steam achievements appeared fine with no crash.
This crash happened both in Fullscreen and in Windowed mode.
