@orangerobot Were you playing with any mods?
In the Create Game screen, which Game Type did you have selected (FAF, FAF Beta Balance, FAF Develop or Nomads)?
Also, please go to client > top left menu > Show logs folder > logs > sort by Date Modified. From there, drag/drop the most recent game log file (should be of the game that you experienced this issue in) into here so those that can help (not me) have that data to look at.
