I have been playing Star Trek: Birth of the Federation for years now (still hooked) but not once have I ever gained any science research points from science specific espionage. Is there a reason for this? Is it just me or is this actually a bug in the program (or designed this way)? If so what is the purpose of actually using up intelligence points on science espionage?? I have gone through the manual many times and it implies that you can gain science research from intelligence but I just don't see how.
I think it's a bug. To me it ought to be a feature, too.
Edit: here is something I have found in a guide:
So I recommend on trying it with the Cardassians next time or try to patch your game, have fun :)
