It's just a coincident or everyone having this I don't know but it's quite helpful.
Today I started crafting missions and thinking for 5, 6 everyday for craft some new items,I completed 6 missions in last 15 hours and got discarded pizza 4 time's out of 6 missions.
Four discarded pizza mean four instant energy boost, but unfortunately I have only 2 pizza boxes I can't store them for later use.
So I started few small missions to consume more energy and these missions almost returned my starbits which I have spent on crafting mission (Each crafting mission costs 1000 starbits)
Everyday I learn something new about Rising star game. now I'm after some crafted cards I don't know how long it will take me to mint this card but I'll keep try until I get this one.
let's get back to discarded pizza. when I got 4 discarded pizza in 15 hour so, I thought discarded pizza should be exchangeable with cold pizza slice.
Let's suppose if we have 6 pizza boxes and all of them have discarded pizza in there then game should have a function to exchange 6 (more or less) discarded pizza with cold pizza slice.
that's how rising game dev can introduce a new reward or mint fuctions to convert discarded pizza into cold pizza slice.
this is my thought maybe it's not possible.
