Episode #5.2 - S5-E2
Corrected entry: During a scene in the Drew's house where Lady Edith is visiting Marigold, the sound of a cellphone ringing in vibrate mode can be heard repeatedly, at first very faintly and then more loudly after Lady Edith exits the room.
Corrected entry: Mr Carson says he has "registered" the house in the name of him and Mrs Hughes. Not if this was 1924! The Land Registration Act was introduced in 1925, effective 1 Jan 1926.
Correction: The Land Registration Act of 1925 was just an extension of an already in place land registration system. Land registration was already in effect, starting with the Land Registry Act of 1862. Certainly no mistake that he "registered" the house in 1924.
Correction: It's not a mobile phone, it's a sheep bleating outdoors.
