not sure what number mission this is.. 6? 7?

anyways, i get to the point that i need to get thruth serum, and the counter won't tick.. i have 19 professors and ran the game for 10 years and nothing.

i fired them all, ran a few years and rehired, and still nothing..

any clues what is up?

PS, i have a game save with the bug active if you would like me to send it to you.
