I would think that she forgot. Unless you had received another pair of ears in your inventory, while you were afk at some point, and win at another event? That's possible too.
Usually she will take your friends title, and they never show in your inventory, regardless of when your friend signs in.
I would ask your friend if she/he has ears in their inventory. If not, she forgot.
Hopefully these ears become tradeable at the end of the month. As there are many people that have multiples, before Hosts were taking requests for gifting.
