Kerbal Space Program

Playing the first Making History DLC Mission: Dawn of the Space Age

After completing the first craft phase and during the K-7B Sounding Rocket build phase.

Entering the Tracking Station leads to a state where:
You are unable to leave the Tracking Station without causing a complete lock-up of the game.

Windows reports KSP as un-responsive and you can force-quit.

This happens if you attempt to "leave" or "launch" out of the Tracking Station."

Very annoying as being able to check the locations of mission objectives in the Tracking Station is very convenient.

Start -> Play Mission -> Stock Mission -> Dawn of the Space Age

Complete first section of mission and return to Space Center.

Enter Tracking Station.

Attempt to Leave Tracking Station.
