I can't swap weapons anymore in Single Player (Campaign) ME3
Yesterday (Saturday, 13 October 2012) I played Single Player for the first time in several months. I tried to swap weapons at the Workbench in the Normandy Shuttle bay, but was unable to do so. Whe...
Going to ask the obvious question here, but have you tried restarting the game? Happened to me a couple of times, but when I reopened the game the bug wore off.
