Was it removed? The "add to wardrobe" and "add to trading card collection" when buying stuff are still there though... And I know that the plushie/beanbag I bought is not in my collection (I checked)
Wait, that's weird. If it's not in your collection it should show up. Duh. I'm going to try this and come back with an edit. [EDIT] It is showing for me so maybe is the browser you're using. I am using google chrome.

I use Google Chrome too (without any adblock, for the record), and all the "Add to" things show up for me except the beanbags.
I am using an adblock so definitely the one I'm using is not the reason either.

It's okay now. I guess something just went wrong either with my net or browser or something. thank you to those who answered :)
