My outbreaks drops in Zombie Slayer disappear

While I am doing the Outbreaks, I can see the count of how many of whatever the drop is.
But once I get off that screen onto something else and come back the count starts over.
If I go into my Inventory, the drops are not there either.
For instance, I have 4039 Zombies killed in the St. George Subway Station, Toronto Outbreak.
However, I do not have a single Subway Car in my inventory.
Someone please tell what the problem is. It does this on both a laptop and a desktop running Win7 Pro.

 

the drops are most likely destructives

destructives get used up quickly when battling

if its not cause your battling then im clueless to

 

As Atheistic stated, all outbreak drops in Zombie Slayer are destructives (they´re used in fights automatically) so most likely you´ll find them before you start any fight, but not after you fought enough times to use them all up.

 

Thanks to both of you for the info.
I didn't know that they were destructives.
I would've figured a a subway car was a vehicle, My bust.

 

i thought the same thing at first bout a few of em

then realized all were destructive

 

In all honestly, i would have thought someone quite as knowledgable about kano as you, would have known that outbreaks in ZS only drop destructive items.


Too much time spent sailing the fifteen seas, evidently. Not all that much clue about just what is breaking out all around you.
