We appreciate you letting us know. To confirm, is this the edit you made [i] where you re-enabled the script?
Indeed, that was the edit -- I had enabled enterprisey's reply-link for a while and just uncommented the line so I could just wait and see when it would start working again. Some time after uncommenting, it actually worked for a bit -- see e.g. the tags here https://en.wikipedia.org/w/index.php?title=User_talk:Blablubbs&diff=prev&oldid=1002953117. I'll keep you up to date in case it unbreaks again.
