Around 39 minutes: When Hannah's Dad is at her place and they're looking at the wall where she maps out links between suspects, she puts up a new photo and writes "Seagrind". Due to lack of place, she clearly has "Seagrin" written to the left of the photo and the final "d" on top. In the next shot, same scene, the entire word is suddenly appearing completely to the left.
It's also strange how at the bottom right the "G" is written differently in the Dutch form "zeegrind" and to the left in "dredging".
