I managed to get the Neferu's scene, was not repeatable tho. Neferu and the other would just "smile at me" when trying futher flirt attempts.
As for Relics, i cannot say for sure if they are working or not. (Says the guy who got the 25% Birthrate relic first and always had about 45% Children in the population)
I also got ideas for Relics, Relic-Buildings: Relic-Bakery, automated Bakery that just needs grain to function. An automated Arrowtower and so on.
