[Video] - Why did everyone suddenly collapse on the escalator?

[UltimaOnline]

Even if the escalator malfunctioned and the speed suddenly increased or decreased, it doesn't make sense for everyone to collapse at the same time. Even if the steps suddenly turned flat (macam travelator), I wouldn't collapse, would you? So wtf is going on?
