My suggestion is to add a message saying you redeemed the costume, the hubtitle, and the avatar(saying what they are) like for example:
You redeemed a space ranger costume, “galactic explorer” Hubtitle, and the space ranger avatar
Yeah so that would be a nice small change
Explanation for the suggestion
So I have been grinding quests for a long time(veeeery slowly), and I recently got a costume gift. I got the space ranger costume. So it said when I unlocked it that it successfully unlocked the costume. So I checked my Hubtitle locker because I really wanted the hubtitle, and it was there. It had never told me it unlocked it though.
Thanks for reading, and please leave feedback!
