Espionage issue

[Hafenguy]

In my current game i spend about 2400 Espionage points in my neighbour the mongols. Points needed for looking into the mongolish cities: 2100
Then he declared war.
After 4 rounds of War the points needed for City infiltrating remains by 2100.
And then in round the needed points increased to 3900.

The cost for spy missions didnt increase.

How is that possible? Was that a Counterespionage mission from a mongolish spy?

I let my spy Do a Counterespionage mission in the mongolish empire. After that I need 3600 points for infiltrating cities.

What did the mongols Do and can i Do anything against it?

TBH, I am quite fuzzy on how espionage works, but it is mostly untouched since vanilla Civ4. So you might want to read some vanilla BtS espionage guide I guess.

I have Posted my question in the Espionage guide thread from kaitzilla. He has done some impressive work with his guide and could answer my question.
He was wondering whether realism invictus has fixed the Bug that the AI didnt use counterespionage.
Here is the link:

To be quite honest, we've been around for such a long time that I can't say for sure - but I guess we did at some point, he illustrates it quite convincingly.

I think the AI ran the infiltration mission with a great spy that instantly gave it 4500 EPs against you.
