The watcher set is a known issue and there are many threads on the topic already. However, the Royal Armor is not an issue, at least I was able to craft it myself just earlier today. 
From my understanding it (and I do not know 100% that this is the case for certain) has to do with the 3.0 update. They appear to have been removed / deactivated behind the scenes probably as a back end update regarding the upcoming Black Lotus Bazaar.
