If a catalog version has been deleted, the Game Manager links to the catalog item stop working, even if an updated version of a catalog has the same itemId in it. (repro - create a copy of a catalog, grant an item from that catalog, delete that catalog, go to the inventory and click on the item's links)
Since catalog versioning requires catalogs to be deleted, this is unwanted/unexpected behaviour.
(you can see this behaviour on 9A7AE96546CEE8C4 in 6263)
