There's a bug I've noticed, that crops up rarely on the Primary Docking Port level. I've only ever had it happen to me once so far, but there are others who have reported this too. A bin with an e-mail sometimes appears far below the docking platform beside the fCon cruiser. It's not supposed to be there. It should be level with the platform so you can reach it easily.
If the bin appears below the platform, there's no way to get the e-mail and come back safely. You either have to ignore the e-mail, or restore from the last save before you entered the level. (I'm not sure if the autosave will keep causing the bin to appear below or not.)
Is this where you can't reach the bin, Kia? Or is it somewhere else?
