I think Royal cut lobster out of any cruises that are less than 7 days. The 3/4 night cruises generally do not have lobster, which is the route Liberty of the Seas is on right now. As soon as she gets back to Europe with a full 7-night sailing the lobster tails will magically appear back. This is the reason why Freedom had it on the menu and Liberty didn't. It's a cost thing; 3/4 day cruises are considerably less expensive than a 7 night.
