Incase anyone missed the memo I must have missed, you can hand in the Treats for Greatfather Winter (Cookies & Milk) straight from your Warbank.
I went ahead and farmed the eggs on my rogue and made the cookies, had tons of milk in the Warbank anyway and to my surprise (no idea why it was a surprise but it was) I could hand it in, thankfully I didn’t mail around all those cookies like we used to or even have to to go to my Warbank and withdraw them.
