INCORRECT DEFINITIONS – Clean Crosswords Review

I enjoy this version of crossword. However, from time, the answers are not always correct according to dictionaries (multiple). Today the puzzle asks for "auditory organ" and the answer is "vassal" which according to all definitions I found pertain to feudal times in history or a game platform. I found no reference of vassal to auditory organ. I suppose the crossword author has better or different dictionaries than the more common ones. .
