Cilivization Production times change after turn?

civilization-5

Solution 1:

I can think of several options that can affect your empire-wide production:

  1. A golden age just ended
  2. Your happiness is so low you entered the "very unhappy" stage, which halves your production output
  3. You chose a conflicting social policy tree and your empire has entered anarchy
  4. You have a railroad network which was suddenly disconnected, so you lost the +25% boost in all cities
  5. Your AI decided to switch citizens to something else (e.g. gold, if you need it desperately)
