I got a notification saying one of my friends sent me a Trex Giftbox. However, I can't find it in my inventory and I made the notification go away so I can't find anything to click on that'll take me there. Where do I find this? What happened to my gift?

Go here :) https://subeta.net/explore/gifts.php/gifts

thank you! I always forget that exists hehe

For those who wish to navigate there instead of following a link, it's in Arctic Frost. The middle left of the image has three buildings next to each other, the middle one looks like a present and has the hover Arctic Frost Gift Center. Click on it and choose the link on the left side called Gift Wrapping. Then go to the middle vertical link called Your Gifts under the image of the gift wrapping elf. Your Gifts is paginated by month so right now it'll show what you got but sometimes around the turn of the month you may need to go backward or forward by a page.
