So I've been going back and forth between clearing the story quests (Which can only be accessed in Multiplayer....that's new to me....) and raising my mag. I got done with a run through Episode 4 trying to get some better armor and suddenly all of the Government Quests in Episode 1 are blanked out, and when I click on the current bottom one, which should be 3-2, the game freezes. This means I can't even get into the ruins yet. Is this a known issue, or related to something else?
