[outdated] about ITEMTYPE_COLLECTIBLE being bound to BACKPACK

I don't know where to post this, but i'll try here again.

so ESO 2.1 patch note :

•Monster trophies now work more like fishing trophies: when you loot one, you automatically receive achievement credit, rather than having to use it as a separate action.

I already tried to ask about these items (monster trophies and rare fishes) being not bankable anymore (tested on PTS) on the Eso forum, but it was burried in 10 minutes by a truckload of epeen balance topics. One of the only answer i had was the total denial that it was even possible.

Is it an error due to the introduction of new keys in this catergory? (why aint they trophy anymore like the undaunted keys is beyond me)
I still hope it is because it make no sense whatsoever to promote the change with the sentence in the quote above if it isn't.

So I know, i forgot to actually ask a question in the other thread when i asked about it, so here it is :

Is it an error or is it intended?
If it's an error and will be looked into it, what API function allows me to reach these values ?

CollectibleItemType * COLLECTIBLE_ITEM_TYPE_FISH * COLLECTIBLE_ITEM_TYPE_NONE * COLLECTIBLE_ITEM_TYPE_TROPHY

Thanks for reading (and hopefully answering)
