It looks like the UP doesn't remove cultures as they're conquered/surrender/defeated. Sure, the other civs have vastly outpaced them in votes, but they shouldn't show up at all.

This is a pretty small bug, but noticeable. Some of the tech text and event text is Human specific; I was playing Arcean (not sure why, I guess I liked their bonuses) and every now and then I came across text that said something like "With this invention the Terran race will spread across the galaxy etc etc" when it was ME inventing it. The Terrans were in this game as well, but the invention was definitely mine.
There are some typographic and informational bugs in the "Report" window that seems to happen at the "LOW" level. The middle and the no-espionage level seem to be fine. Namely, the first 2 paragraphs have 2 periods after them. IN addition, the second paragraph, ship information, has the ship heading towards ". (quote period). There's nothing in the quotes.
I've researched some techs that give me a lot of starbase modules .... but when I build a constructor and go out there, I only have a couple listed, generally a mining boost and an offense boost. Why is that? And how do I tell what starbase modules I really have, and what starbases they're available for?
