How do counter spies affect the success rate of AI spies siphoning funds from my city? Do they lower the success rate or do they have some base chance of intercepting the operation while success rate remains the same? I assume the latter, since the AI succeeds just about every time, and since all the opponents are targeting my richest city, I keep losing gold at atrocious rate. I have tried to place multiple counter spies on the districts adjacent to the city center, to no noticeable effect. I was hoping that the chance of intercepting the enemy either stacks or then each one gets a go at it. How do multiple counter spies protecting the same district/city center work in practice? What really baffles and frustrates me is that enemies succeed in their operations in spite of counter spies something like 9 out of 10 times, and my stupid thumb twiddling counter spies are never able to capture any of them. If I attempt any offensive spying operations myself, the given success rates are nowhere as generous. Does the game boost the enemy success rates depending on how well I am doing overall? Meaning, if I am winning, the enemy spies get a bonus to their success rates. Finally as I understand it, the amount of gold that a spy siphons is the amount that the target city accumulated during their operation in that city. However, it looks like every spy stationed in the same city gets that same amount, which is illogical, as they in effect are stealing the same funds multiple times. What a "fun" mechanism to bankrupt me while I can't do anything at all about it! Or can I? Advice welcome.
