Are you sure your in the right part of town? Maybe a new part unlocked like the upper class part or a different section of the slums.. somewhere you couldn't go before. Because if your suppose to do those things then it would definitely show up if it's in that region. Also make sure your in the right town and place. Lastly.. if all else fails, I think you can replay the memory block fr4om the beginning, instead of continuing it. See if that works. Let me know if any of these things helped you. I'm sure your just in the wrong part of town, or in a different city all together.

which Memory Block is it? Which assassination? You should tell us atleast the memory block your in since you do have to look at that every time you load the game. Then we would be able to tell you if your in the right spot or not.
