I've made it (in a pending update, so it may or may not affect the next host event) so if a room is featured (has the mickey icon) it will be searchable. There's a 15 second lasting cache of the rooms in the main guest room list, which doesn't apply to searches, so if you search for it in the same way you did before, it should show up once the room is open... It's not the same, but I had to exclude staff rooms from searches ordinarily because some people found ways to abuse it. Ordinarily it wouldn't be a punish everyone for this thing, but in this case it creates quite a lot of work for the moderators to undo, so it's a necessary evil I'm afraid.
