After an event for like the 1st 24hours we should be able to sell any extra items left over back to the warden; for a low rate. or exchcnge them for other items. I dont mean prizes. Particularly, I mean like the random power thing or disc from the bride mission that never got sold or the gold tickets from this one.

And/Or

In new missions as a special mission using what you may have left if you meet the quota or whatever someone is willing to sell if u dont. to build some special amenity or access to a special location (like with left over golden tickets)

that way if you sold them back to the warden then whatever they could have got if they kept them they miss out on or if you dont care you can sell what you have left to whoever wants that amenity.
