Continuity mistake: When Gran and Saffy are are talking to the new best friend at the end of the show the first thing that happens is that a wine glass next to new best friend slides along the table (you see this happen on screen)then it changes from wine to water back to wine.

Revealing mistake: Saffy is ironing her boyfriend's shirt and when she has finished he puts it on just before asking her to marry him. When he buttons it up he does so with the buttons and holes misaligned by at least 2 button-holes, and with the collar obviously at an odd angle around his neck.
Audio problem: In the scene where Eddy is in the helicopter and shouting down to Patsy who is on the ground, she says something like, "I'll meet you down there!", but you can tell that line was pre-recorded because her mouth moves completely out of line with the words.
