Hourglass by Déja Augustine Still Supported/Working?

I just recently added this script but it no longer seems to work after I delete the hourglass token and then add it back at a later time for another encounter.  The graphical/visible countdown only works the first time.  I use it in conjunction with the OnMyTurn API script.  I cannot find any recent news on it, so I was wondering if it is just no longer supported. The only way I've been able to get it to work again was to resave the Hourglass script. Anybody here had this same issue?  If so, what is the fix?  Or am I just missing something obvious?

I'm not familiar with the script so can't answer your main question, I'm just responding to the question in your thread title. Scripts might stop working due to changes in Roll20, but they are still 'supported' - if someone steps up to fix the script. I hope that's clear. There's nothing stopping someone from doing that.
