Suppose you noticed that the amount of trophies earned by your township has decreased.
There can be 2 reasons for that:
  1. Someone from your township members left the township, and therefore all the cups earned by that player were removed from the township's festival score.
  2. There were dishonest players among the city residents. Dishonest players were blocked, and their trophies were deducted from the township's result. Now the result contains only honest players' trophies.
