When playing superbugs a dialogue box comes up which states 

you have lost connection to the Internet, online game features will no longer be available.  

Any nodes you have completed within the game are lost. All connections to the Internet are fine, no loss of connection. To rectify, game has to be closed and restarted.  It appears to be linked to the game and steam. It only started happening this week. I am worried this, will Impact on museum.  Could someone please let me know if this is something you already know about, or, what can be done to investigate this issue.
