all the events for the Yor is based on organic life, why would the Yor care that tourist are dying due to toxins in the air while looking at a beautiful sunset, and so on.
With you on this one, been asking them to add filters to the event system since Beta5, it's the reason I don't play as Yor or other synthetics at the moment, it's very immersion breaking when you are playing.
One should be able to build sensor satellites, instead of producing 1 unit at a time, perhaps a group of 5 that can be sent to different locations.
I can't see any reason why you should be able to do this, you can produce them one at a time effectivley like other ships.
On the AI and declaring war it's certainly far from random and if you know where to look in the diplomacy screen you can see what factors impact your current relations with any race as well as the level of those relations, this should give you a good idea why someone has declared war. I find it's often a reflection of you being percieved to have a weak military.
