Sorry, I again misinterpreted HaChu's scoring. Which was indeed such that there was no mate in 16, but that the checks could only be kept up for 17 moves. So you are probably right about the Flying Ox/Whale copying mistake. The MSM clearly depicts a Flying Ox in the diagram for this tsume puzzle, though.
