If you keepsake a Ruinous weapon apparently it doesn't put the item in keepsake but it still gives you the cosmetic.

Meaning you can still use the weapon and also the cosmetic override.

Can anyone confirm this is how it's meant to be? Apparently it's the same for weapons like ECB as well..... but the wiki does not mention if it is.

EDIT: Can confirm it works like this, but if you delete the "Replica" cosmetic you don't get a key refund or anything.
