Here's a few I noticed:
1. One time I was launching a colony ship from the planet screen and lowered the number of people on it. When I launched it the screen went to the galaxy view but there was no ship. Double-click on the star and the planet's population has been reduced by the amount I picked but the colony ship is still orbiting. Repeated this two more times. Finally, just left the number of people on the default of half the planet population, and when I launched it worked normally.
2. When I would put a planet on the "Republic" governor, it would build trade goods that were unavailable anymore. For instance, it would start building Diplomatic Translators after I'd already built them.
3. Music during diplomacy and the cutscenes is choppy. I have a 1.2 Ghz Athlon, 256 MB RAM, SB Live! X-Gamer, most recent sound drivers and DirX 9.
4. Would get messages informing me that other empires had built a wonder after it had already been built by someone else.
All in all, great game! I know this isn't very detailed (I'm a progger too) but it was my first game. I will pay closer attention next time.
