Thanks Jay. I checked but my twit list is still completely empty. Fortunately
for this time, new messages have arrived in the affected echo and the issue
is gone for now. I have had this issue on both Windows and Pi versions of
Mystic A46.

I'm just about ready to migrate everything over to A47 so I'll at least be
able to see if it's perhaps something that's been fixed in A47.
