Hi, with the latest upgrade to ATT 2.3.2, it seems that it changed around some things in the Crafted Item category of which I believe is unintended.

Firstly:

As seen above, this is now showing up for me, but as the tooltip claims, it is already learned so I am uncertain why this appears (as it does not have any sub criteria as most collectibles do when you click it).

Secondly:
Some TBC crafting items seems to have gone away, I'm only aware of Tailoring things as I play a Mage but I am certain there could be similar issues for other professions.

With the 2.3.2 update, I went from having 7 to 3 missing TBC crafts with the following now marked as completed:

• Battlecast Hood - https://www.wowhead.com/item=24267/battlecast-hood
• Spellstrike Hood - https://www.wowhead.com/item=24266/spellstrike-hood
• Whitemend Hood - https://www.wowhead.com/item=24264/whitemend-hood
• Spellstrike Pants - https://www.wowhead.com/item=24262/spellstrike-pants

My initial thought was that the data collector could perhaps have wrongly marked these as their set bonus have a tailoring requirement, but anyone can learn the appearence despite being a tailor.

For reference, these 3 items was NOT marked as collected with this update:

• Manaweave Cloak - https://www.wowhead.com/item=24260/manaweave-cloak
• Hands of Eternal Light - https://www.wowhead.com/item=34367/hands-of-eternal-light
• Sunfire Handwraps - https://www.wowhead.com/item=34366/sunfire-handwraps

Sorry it took a while to get back to you, but it seems that after the ATT update that came shortly after this issue was posted, it was fixed again, so perhaps it was a caching issue on my end

Looking into the fishing journal... it's not supposed to think it is collectible in Retail since player's don't really "learn" the spellID associated with the item from the API. So somehow that got attached again.

As for the Tailoring craftables... you're saying you never actually learned them, but they are now showing as 'collected' ? Are you on Unique or Completionist? Can you put on Debug mode and show a screenshot of the item tooltips?
