"This item is in your inventory" unaware all exotics were reissued with new hashes

New versions are attached to collectibles. Old versions in inventory do not trigger the checkmark.

I think to fix this, we'd probably need to switch from calculating ownedItemHashes to calculating ownedItemNames, or maybe even some more complicated key if multiple types of item can have the same name. Not fun.
