Forum:Head of state major bug?!

After killing all of the slavers etc I told Hannibal. However, the quest goes no further, he just stays there. I have waited 72 hours for him to get to me but still nothing. When I checked back, he was still there, and the only options are "so you used to be a slave" and "goodbye Hannibal".

Hey bud, Kenny Powers. Is it possibly that you didn't do the sidequest to the Muesum of History to get Caleb Smith his picture of the Lincoln Memorial? I don't think that's necessary, but it Helps. Did you kill Leroy, the boss of the slavers at the L.M.? You might have left a guy alive, possibly in the mechanical room to the left of the memorial steps as you look at them. That's most likely. Good luck.
