Noticed this with update as of 2/20/2012. When trying to access the Full Supply Depot from the Mission introduction page the inventory does not initially show up. You must click the Return to Missions button and then re-click the Show Full Supply Depot button for the lists to show. I waited to see if maybe it was a loading issue/time issue but leaving it did not bring the supply list up. Also, if you try to search for an item, no item comes up and the Return to Missions button doesn't work while there is text in the search field (if you have done a search). Once the list shows up everything seems to work fine.
