Just incase others missed it... the fix has been applied, but by way of a new feature.
It\'s not enough to simply tick \"Required\" in the field parameters, but rather you need to tick REQUIRED in the actual Event Management screen when choosing which fields are to be displayed.
Just to clarify... ticking \"Required\" in the Custom Fields screen does nothing.
But ticking \"Required\" in the Event management screen at the bottom does work.
Those that already have fields setup, will have to go through each event and tick each field... Time consuming but atleast it finally works.
