PFS and Spear of Manhunting

[morbon]

Pathfinder Adventure Path #67: "The Snows of Summer"
Equipment: all equipment except cauldron of overwhelming allies and spear of manhunting are legal for play; Spells: flurry of snowballs, ice spears, Irriseni mirror sight, and snowball

So, why does the official PFS page say that the Spear of Manhunting is illegal for play, yet the sheet for "The Snows of Summer" clearly lists the item on it with a full item description?

Is it illegal because the site says so, or is it legal because the chronicle sheet says so?

[Artanthos]

Specific items granted on chronicle sheets usually take precedence over the allowed resources document.

The Spear of Manhunting is illegal unless the character has a chronicle sheet allowing him to purchase it.
