I am a ghost!
I entered the parlour at Mrs Hatch's at just before 00:20 UK time. Mr Thomas Blakemore and Clara McTavish were in there, but they couldn't see me. They could 'hear' me (i.e. read the chat box), but couldn't see me until I moved out of the room. (With suitable cries of 'Wooooooo....' and a flutter of ectoplasm.)
I was wearing a skirt and spencer from the marketplace (in case it is a rendering problem).
I've only just seen this thread... I was in the parlour when this happened, and I did see dagngayt ((sorry, can't remember character name!)) reappear just as she was leaving the room. This was presumably after she'd finished using the writing desk, so perhaps this is an issue with the desk as well as the clothing? Thought it might be worth mentioning.
