Change the criteria for obtaining ''Gears'' (for Hero) in ZHG Locations.
Introduce the chance to throw into the trash the Hero Gears received from ZHG locations (not just sell them!).
Every day I run 60 ZHG locations and I have already been invaded by dozens of these Gears in my inventory (and temporary inventory too!), since a Gear is released for every ZHG Location completed! 
For today, in my program I have again further 60 ZHG Locations to run (as every day!) ... and I do not know how to handle them, since to sell each one of them it takes even 1h and even 3h in some cases!
My most important Gears are lost, because there is no more space and I can not replace them in time with other Gears in the "final inventory".
Alternatively it would be much better to receive a Gear only after that several ZHG Locations have been shot down (such as the Bank payment, which gives you units after having destroyed several ZHG units) ...
So do not give us a Gear every time you destroy a ZHG Location, but 1 Gear in relation to the amount of ZHG units destroyed! (regardless of how many ZHG Locations you need to break down to achieve this result).
