Hoarding Prospectors

I've been dumping on my neighbors :mrgreen: even bought a few extra, well..just because it's fun and to make up for being a lousy neighbor for the past few months. Unfortunately about half of them apparently haven't started playing or there's a glitch, because I can't drop on them. ...and then there's the invisible ones, like Newcastlenia :(

This event is a lot like last years Halloween when we dropped the purple nightmares. If memory serves me, there were plenty by Act 3. But these prospectors are a lot harder to see/find.
