I noticed during the Airport City Event that when you tapped on the icons that indicate a neighbor visit to a Gaming Studio, that sometimes I would receive items from the Heroes of Our Time collection. To be clear, these were received when tapping on the visitor icons, not when tapping on the standard coin reward. Not sure I've ever noticed any other buildings rewarding collection items as a result of neighbor visits. Is this unique to the Gaming Studio, or does this happen with other buildings as well? If not, seems it would be a good idea for GI to encourage more interaction with neighbors and/or connecting with more neighbors.
