I was wondering...If another civ's spy enters your city will you know (assuming that you don't have a spy) what they did (Steal gold, great people...ect) or will you just be left to guess.
not sure... but it does tell you when the enemy destroys unit fortification.
Yeah it tells the person what you've taken. I only know this because late in the gave I love to use spies to cause chaos >_>;;; and occassionally the people who were my 'allies' (I play free for all) get pissed and declare war on me. xD They normally also demand a great person or gold or w/e it was I'd taken. =P So they not only know what you took but whose spy it was.
