I'm also wondering about the Pop Idol bug since my games do the same thing... a max of 50% culture.
What exactly do you guys mean when you say a "max of 50% culture"? Where does it display this figure?
while on the topic of achievements i would like to go slightly off topic.
Does completing any of the achievements give you any bonuses other then the bragging rights to to post screen shots showing you found space ponies?
Nope. Though you've gotta admit, that's a hell of a bonus.

Pretty sure I know what you're talking about and it's not a bug. The yellow entry is their actual armor rating. The green text is counting as a bonus modifier from the research showing you what it's adding to the base value. Much like antimatter regeneration, shield restoration, etc.
...I'm not certain about this, since I'm not bothering to check right now, but I'm pretty sure the armor value simply displayed twice. Not as a buff, in green or anything, just another armor listing a few lines down from the first. Maybe later I'll go take a screenshot.
As for typos, there's a misspelling in one of the Vasari fleet logistics upgrades where 'Seized' is spelled 'Siezed'. Not sure how to let the devs know so hopefully they'll pass by this thread.
Well, we
could always email them.
Do you know what the tech is called, so we can have a detailed listing of typos in case they wander by?

Do you actually get a planet through Culture. I completely iso'd a enemy planet and never got it in 3hrs so just bombed it. Culture is shitty - only works for the AI lol
As far as I know, culture can only render planets neutral, not actually capture them for your own use.
