As a heads up, this will get automatically get moved to the "Insufficient Information" sub-forum as it's not in the correct format as outlined in the stickied thread at the top of the page, out of curiosity, is this AF or Relic reforge upgrade? Instead of saying you are trading the right items, post what it is exactly you are trading, it may be something simple like Griffon's Leather instead of Griffon's Hide.

Are you trading 8 chapter 10s definitely? Since it's AF, are you possibly trading Sif's Lock instead of Sif's Macrame?

The gist of it is, anytime someone has had a problem with Monisette it's usually user error, hence why I'm leaning towards you trading the wrong Sif's item.
