I've started noticing this more in my games and so I'm a bit confused if this was a change I just didn't notice in the fall patch for G&K, but city states I liberate are only what can best be said to be "momentary" allies in that I only get 60/60 pts when liberating them. So guaranteed on the next turn I have to give them something to stay allies, while I'm also fighting off the people I liberated them from. This makes no sense to me. I thought it was different earlier but perhaps I'm mistaken?
