v0.77
The AI just offered me a trade which included the techs 'Survey Ships' and 'Extreme Colonization'. I expected to get a free survey ship from the 'Survey Ships' tech, but none appeared. I then checked the Technology Library and see that I DID get Extreme Colonization but I DID NOT get 'Survey Ships'.
The deal occured in the previous turn (65) and the attached save called 'incomplete trade.zip' is turn 66.
