To address another element related to the Trade Orders as i missed this bug report :
https://trueuo.com/threads/trade-orders.3213/ and it is already closed :
I wish to add that i hit few times 'Book' in a Trade Order.
For one order it was not the any of the 3 types of book sold by NPC, or 2 books players can craft (with 100 or 200 pages if i remember).
Atm i am just carrying the 3 NPC books and if is not any of those i am skipping the whole trade order.
All what players see is 'Book' and there are plenty types of books.
Quite probably same will be with 'Flask' and maybe with 'Pigment/Dye' (not the regular dye from tailor).
Got those too and when i was unable to find those items at any vendor in like 3 cities i also decided just to delete those orders.
Creating new thread as previous one was closed, but i assume they can just be merged.
