It is so mean that the level has been reduced from level 5 to level 0 for answering a calls.
I take calls in the middle of a level, for example) Level #6488. The Calling window is active and put Farm Heroes Saga in the background. End the call and re-active Farm Heroes Saga. The app will restart, the level will automatically fail, and Bonnie's boosters will be dropped to level 0.
