Playing campaign normally until this mission.
I cannot complete the objectives because the session ends unceremoniously.
It says that all the AI parties have been defeated.
It says that Nova’s forces have been defeated.
Forces are restart from last save.
It started happening at the end of the sewers section but I managed to run past the last few defenses.
However, after the cutscene where you receive instructions to disable the security stations before the speech is done, the defeated forces screen appears and the game session ends.
I’ve never seen this type of notification in a campaign mode game before, but I’ve seen it in multiplayer matches of course.
