With 1.02.039 I have seen two oddities that I have not previously seen with the other versions. I'm sorry that I have not tried out 1.02.040 yet, but just in case these were not yet addressed/reported here goes.
1. After I have built one of the trade goods (years after in some cases) the dialog box at the beginning of the turn will tell me that one of the other civs has also built it and they have exclusive rights yadda yadda yadda. I take a look and I still have it and also take a look on the trade screen and they do NOT have it, contrary to the message. This problem does not seem to happen for galactic wonders though.
2. Typically when a tech is researched which leads to new improvements that you can build (yes, I realize some techs no not directly give buildable improvements) these are listed on the tech-complete screen on the right side in yellow when the tech is completed. Last night no matter what I researched it never listed the new building opportunities. Minor, but that kind of game feedback is helping me learn the tech tree better.
