Zadra Doesn't Advance During the 'Escape with Zadra' Objective in 'A Lot to Process'

When playing the 'A Lot to Process' story mission, Zadra may stop moving entirely or begin running erratically during the 'Escape with Zadra' objective, preventing the mission from being advanced and completed. 

Workaround: This can usually be resolved by restarting the game itself, but can also be resolved by restarting 'A Lot to Process' from the active mission menu.
