4 Cosmos disappeared of my Wardrobe

So its not a bug (or i hope not) but 4 of my cosmos vanished from my wardrobe. I know 1000% that i had them cuz i keep track of everything i acquire in a spreadsheet and in Or Stash. The 4 cosmos are : Epic Net Back Swag, Limited Turkey Tail Back Swag, Epic Toilet Paper Staff and Legendary Pirate Hook Prop. I dont know how it happened but it happened somehow. Sadly i figured it out today while adding the new Halloween Cosmos to my spreadsheet so i dont know when it could have happened.
