In 3 of my 3 games, I had to quit because I lost every year around 5-10 installations and that empires have stolen already all techs from each other ... there is atm nothing you could do ingame, no building and even no counterespionage helps
So here we go, the "all are spies mod" , which gives all races a paranoia counterespionage bonus
of 110%
So when you are now using counterespionage , it should help
don't know, if it is enough or not, we will see !

MOD gives all civ 110% counterespionage bonus
File for 1.0.9.1
works as long as the races.xml will not be changed from a new patch
INSTALL
extract the file and overwrite the same file in the data directory in your game
It only works, when you start a new game, you could see the bonus when you examine a civ
