Soccer Cup: I'm not getting any Energy Drinks from my city's surroundings via Incidents!

In this year's Soccer Cup, you can find a small amount of Energy Drinks in Incidents around your city. 

These Incidents work just as regular ones do, and may contain the standard Incident prizes such as goods, coins, supplies or even Diamonds, but during the event they may also contain Energy Drinks. What this means is that there is a chance every day of between 10-15 Incidents spawning in your city, and some of these may contain Energy Drinks. However, this isn't guaranteed, and these extra Energy Drinks shouldn't be relied on, but simply a little extra bonus for when you do find them! 

Make sure to collect all the Incidents in your city to increase the chance of new ones spawning with Energy Drinks!
