I am playing the Challenge "Epic Game For 3". I won a war over technolgy with 14 points advantage. When resolving, I was only presented 1 out of 3 of the opponents blue technology cards.
The one presented to me is the only one where I have a better blue tech card already (navigation/carthograpy).
We also both have the same technology "Code of laws" (Same Level)
I would expect to be able to select any of the 3 opponents blue tech cards, or at least 2/3 in case "Code of laws" is excluded because I already have it.
Looks like a bug to me.
