Nope... Couldn't do it on Space projects, nor the Manhattan project (well, I guess this one isn't really a "District Project" so that was to be expected)
And actually, this bonus is underwhelming at best!
I just expended a 4-charges builder to produce roughly 80% of my city's production on a Commercial Hub investment!!
Not even one full turn worth of production @_@ For FOUR charges (in hindsight, the number of charges probably doesn't matter. I'm too mad to do further testing on this right now), plus it can only be done on the "Great People" projects apparently, and only once a turn. Whew.
Also:
- You can't liberate a city-state you got from it being captured by an enemy and lost to you through the new loyalty system.
- The Amundsen-Scott Research Station with 5 Snow tiles gives +20% Science, +10% Production to all your cities -- the double yields (+40% Science, +20% Production) ONLY apply to the Amundsen-Scott city itself (the full-on Tundra/Snow one yeah)
