Hello,
Yesterday I removed a CW from my wardrobe (Risky Inky Whiskey) and ended up with a duplicate. (I have already been helped by Angelina who was able to delete the extra for me, but thought it was worth mentioning here.
More in depth: I am using a Mac Book, Safari Version 13.1.1. I was removing items from my wardrobe yesterday, and when it came to remove this item, I clicked on the remove button and it did nothing. The other removals were pretty instant, so I thought I had perhaps mis-clicked, and when I clicked it again, it appeared to move as normal. When I went to my inventory, I had 2 of this item.
Please let me know if there is any more detail I need to add!
