Doe Carcass bought from Trade not counting in Quest

I bought a doe carcass for the questing snake but it's not registering as a quest item to complete the quest.
and this is the doe carcass i still have in my hoard on the far right.



I would make a safe bet that this is probably a bug / known bug.

'Doe Carcass' and 'Small Doe Carcass' are two different items. You need a regular Doe Carcass.

I feel silly for that! Haha thank you much.
