Shadow Broker Game breaking bug after exiting trade center

I noticed a similar problem, mine was slightly different, but with the end result being after I left the center and there is Liara and the other woman in the shootout, but nothing was happening, as in you could not leave the planet and it would not queue the action or any further progress. I did not have a modded game other than other DLC. I think it's just a bug that never got resolved, I did solve the problem by loading up a save from where I first entered building, it seems to get the correct version of the game (instead of the glitch version). But if you try to load it from the autosave before they start shooting each other (if you had a glitch version, well, you have to go back fairly far into the mission, but you don't have to restart). A main problem with this mission is that you can't leave the planet, other than just restarting the whole mission. I'd recommend several saves if on Shadowbroker, and a save from one on the Normandy but before you accept the shadowbroker mission, just if it messes up on someone's game. I still have the messed up version of that save I think, unless I rewrote over it, but I might be able to give a log, though I forget all the steps on what I'd need to do to report this bug. But unless I still have the save, I'm not sure how I'd prove it happened. It must be a low instance, because it seems like only a few people have ran into this bug, I'm not sure what would cause it, but it's the first huge bug I've encountered. That is one of the longest DLC's, it's a really good one and well worth it, plus it seems to give a lot of back story, and fills in a lot of missing info to the story. I admit, this bug worried me because I wasn't sure if I would be able to finish the game (luckily I'm a save-aholic so that actually helped) to revert a game.
