Por que eu sou desconectado quando tento ler um comentário?

This happens when you open a comment that Scratch can't find in our database.  This usually is because it has been deleted, but can sometimes occur for other reasons.  We're working on a solution for this, but it will likely take some time. If you get signed out you can assume that that comment doesn't really exist and don't attempt to open it again.  

Sorry for any inconvenience this causes.
