After fixing a world of a friend, he said he gets a strange error after a while, so I reproduced it and got the same.
It is connected with roboports, got placed down by a construction robot in the middle of two (or more) existing roboports. The new roboport connects these originally two (or more) robot-areas to one big area. After the reconnection progress is done (half energy bar is filled), a message appears on the screen. While the message is visible, you can still play the game like normal.
By clicking "OK", the game crashes to the Main Menu but when pressing <Esc> the game continues.

Re: [0.11.3] Roboport "reconnecting" issue
This is great, because I added this error check to find out how could this happen, and finally it happened 
If you have the save of the situation before it happened, it would be great, as I could take a look at it and solve it.

The save is right here: https://drive.google.com/file/d/0B4HRU8 ... sp=sharing
The construction robot, who places the roboport comes directly after loading from the south.
If more time at the beginning is needed, I could make it
