On my 3-4 play through golden age seen to has nothing to do with it. It works regardless of golden age or not. But once you added certain number of points (overall) it stops adding points. It is really odd.
Not sure why but after a while the add policy function will stop working. Maybe the value is capped at 16 bit Int instead of 32 bit int?
The Add production function doesn't work for Mahanttan Project either.
That option stops working while in a Golden Age. As soon as the Golden Age is over, it starts working again. At least, as far as I've noticed.
The Manhattan Project and the Apollo Program don't work with the construction option. Probably because they're special. One unlocks the atom, one unlocks the spaceship.
Yeah i also noticed that "golden age" prevents adding more policy points. To be honest - its easier to use Artmoney to add policy points. Just add 30000-50000 and you can select everything you need. You can also start "golden age" and use Artmoney to prolong it to any number of moves.
Only options i really need - unlimited number of moves and money, since its hard to find those values by myself.
