The MA WEB site MOMS download file has been fixed for 13.14.4.4 and possibly others, who knows. It was clearly a typo as, for once and unlike the EVO rule rewrite, the Commission minutes actually clearly showed the discussion and reason for the change.
This naturally begs the question who proof reads the MOMS and is it OK to just change a published rule book without giving it a version number or revision number so that changes can be highlighted/tracked? Apparently not
