Launch problem running wild

[Blue8282]

How does one go about completing the running wild collection? It seems that the portable audio player never drops!! I have visited the places that it lists and nothing!! I have also bought the space exploration for 10 greens 5 times and NOTHING!! Hard to launch when items don't drop! Someone please help, tell me what I am doing wrong!!

Easiest way is to get one or two Stone Castles for 12 greens, those drop all items for this Collection on a quite good base. And it is maybe the best pax producing Building in the game with 36pax/h.
