There is a discrepancy with the effect description for the Missionary Center ( and the other 2 equivalent structures)

In the Ideology screen it still says that each Center provides 10 points, whereas on the planet build screen it says 0.1 point per turn.

The same with the Pragmatic and Malevolent buildings.

When tech trading, it would be handy to see if the tech your trading to/from is a specialization tech, and if you already have any of the other techs in that specialization.

The reverse would also be good, ie in the tech tree, show who has the specializations you are missing so you know who to contact (and be nice to so they'll trade)

With an incoming message, some text to say who's calling would be nice ie "Message from Iso the Wise of the Iconian Refuge)

Game is looking good.
