Lost mega-kick! (Dying Light)

Last week pumped a LVL 24 strength and agility. also pimped the 5th level of the legend, all 5 power UPS spent on a dogfight, by the way. Further all as at all: no longer tired in the fight, and while running, the opportunity to safely jump off low roofs.
Jump on the trash heap, too, has changed. If you had landed with a noise on his back, now began to land silently on their feet.
But the main thing was there was mega-kick: on a kick with a running insects flew about 100 metres.
Today went to the game and I was waiting for the nasty variation: kick has become the usual, jump on the trash heap, too, is now happening to grace cakes, and jumps with low roofs again removed HP.
And I have a question: what was it?
Mega-kick was a bug? This is a bug or lack of it?
