The Klingon has a typo: maS'e' instead of raS'e'. I faithfully translated it as "the moon is in the restaurant" and was marked wrong.
I can't find this sentence in the Incubator.
Perhaps it was deleted because of the error you found, but lingers on as a zombie.
Do you remember which lesson of which unit you were doing when you came across this sentence?
I looked at it earlier. loghaD must've already taken care of it.
I've added the version with raS'e', since I saw that that didn't seem to be present.
In case you still need to know, it was in Locations level 4.
Makes me think of Tolkien's poem, "The Man in the Moon Stayed Up Too Late ."
