Suggestion(s)/Comment(s): Make guild furniture knowledges obtainable from an NPC
Details: Certain guild furnitures are very expensive (half or one billion guild funds) to make, and although you can put them into guild storage to share, you cannot get the knowledge from those. Guild funds are much harder and slower to acquire than normal funds, and if several guild members want to get the knowledges, they will make a lot of furniture that might not be used. Those cannot be stored in normal storages, and cannot be sold for guild funds either.
Also, there are a few base furniture items that (according to our current knowledge) cannot be obtained from drops.
To alleviate these, make guild furniture knowledges obtainable from an NPC, thus avoiding the waste of guild funds and resources.

Alternative suggestion: make the top tier guild furniture item (eg. Master's Special Stuffed Belladonna Elephant Head) give the knowledge for the lower grade items (green, artisan, artisan special, master non-special) from an NPC.
