What Happened to Frederick - S1-E13
Deliberate mistake: When August takes Emma to the Wishing Well, the well is not in the same location as later in the series. When Emma and August are at the well, it is situated next to the road (August takes her there on his motorcycle), with a giant tree in the background. In in 1-22 "A Land Without Magic", and every other episode where the well appears, in is situated in a clearing in the middle of the forest. (00:22:35)
Deliberate mistake: Elsa's dress in Season Four is different from the dress she was wearing in the Season Three finale. The new dress is a different shade of blue, and has a completely different design, even though the present day events of Season Four take place mere moments after the end of Season Three.
Chosen answer: Even if one can see the future, it can be somewhat vague and left open to interpretation.

He can sees the future all jumbled up. It is like a puzzle, it is hard to put together, but even when he does put it together it is not set in stone the future can change.
