I finally decided to get around to organizing my wishlist, and it looks like the verbiage that used to say something like, "you have this in your collection! delete?" is gone? Was this intentional or a bug that's being worked on? I have huge sections of my WL for collection items, and I was hoping to clean them up a bit without having to manually calculate which of the 500+ stickers on my WL I've already received.

wishlists no longer do this. Subetalodge can help you manage lists of stuff. I know if something's in Inventory you can un-wishlist it by clicking on the bottom. Can you do this with your collection.

They removed the "You have this item" because of the strain on servers or something

Ah, that sucks. I know I have duplicates on my WL, but short of digging through all my collections and manually comparing them, there's no way to know if I still need it. :/

Thanks for answering!
