Not sure where to report this, but today's featured article includes a link to the 1974 Atlantic hurricane season which, if hovered over, consistently gives an error message "There was an issue displaying this preview". Other links work, I suspect maybe it doesn't work here because there's no intro? Apologies if this was already reported.

There was no intro because the page was vandalized and this somehow got unnoticed by the en.wikipedia community for 8 hours. Should be OK now.
