As of today, untradeable equipment now breaks upon death instead of being able to just run back and collect it gain. 
I'm very in favor of this, and excited - how about everyone else?

New questions to answer: 
 - is there a complete list of items? (Firecape: sure .. Ava's attractor: ?) 
 - how can I tell if my item is on it? 
 - what did Jagex obviously forget? 
  
EDIT: here's the full forum post discussing the update
