Re: Mass Effect Legionary Edition - Race Against Time - Conduit.  Can't progress

If you ended up where you started the mission after leaving the area where you talk to Vigil then you simply went the wrong way.

After exiting the elevator away from Vigil you turned left down the hallway. You're meant to turn right, toward the area that was blocked with a shimmering wall when you arrived. You won't need to exit the Mako again after talking to Vigil.
