Forum:"spend" time in ME2

Hy!

I have a question. I completed all missions (including all DLCs) before buying Lair of the Shadow Broker. I completed that too. Now I have access to the Broker base. At the delivery console, I picked up the 1st delivery. I know I have to "spend" time in the game to get the next delivery. But how I should do that? I still have some dialogue left with Legion. These new dialogue/etc options usually unlock after a mission is completed. But I have no missions left at all. How do I unlock these things then?
