Losing A Key When You Lose In The Void?

[(PSN)IkariWarrior83]

I have a friend who did a T3 survival, but failed the mission after 15 or 20 mins, and the key was consumed.  It was my understanding that if you fail a void mission, the key is not burned.  Did that change in the recent updates?

 

I could understand implementing that to prevent abuse (i.e. I didn't get what I wanted so I lost on purpose), but I think it's also pretty terrible when it's "Damn, I lost the mission, and now I have to go farm ANOTHER key."

 

So, are keys burned at a certain point (like after wave 5/minute 5/etc?) or is it just an across-the-board "you lose you're screwed" kind of deal?

after 5 mins/5 waves/1 round, surival/defense/interception keys are consumed. failing before this will return the key

Bummer.  Thanks for the clarification.
