What I mean is, when you go to Orokin Derelict Defense, you usually get a void key as the 10th wave reward. If you keep going and claim your reward only on the 15th wave, you still get the key.

On both survival and defense (at least for the past couple of months, since I started playing), you'd always keep all the rewards you'd been presented, regardless of when you chose to complete the mission.
