Prevent Wasting Time Looking for Non-existant Zombies

[WonOnOne]

After clearing a Tier 6 mission of all zombies, and spending 30 boring frustrating minutes triple checking every room and triple checking the roof for a missing zombie, and firing my rifle in every room hoping to trigger a zombie, which I begin to doubt even existed, there needs to be a feature that tells you where the zombie is after a fruitless search.  Hide-and-Seek gets boring after a while.

That feature exists. Typically the last 1-2 trigger zones will light up on your hud on clear missions. If that isn't happening, it's either not a clear mission or it is bugged. Log it.
