When Kelly and Logan enter Taft's warehouse, it's sunny with a few clouds. Moments later, when Taft closes the warehouse door, it's still broad daylight with bright sun. But a minute later when Kelly and Logan escape the warehouse, it's dusk and the buildings in the Manhattan skyline have their lights on.
When the press is interviewing Chelsea after the charges against her are dismissed, there's no breeze, and her hair is around her face. The next shot has a rather strong wind whipping her hair around, then in the next immediate shot, her hair is still again-as if there had been no breeze at all.
The night Logan can't sleep and Chelsea arrives at his apartment, there is falling rain vigorously streaking the outside of his window (and later Chelsea's window when they arrive at her loft) but exterior scenes have only wet streets.

The bomb left by Taft in the warehouse has a digital countdown clock, yet it ticks as if it is a mechanical clock.
