I have been using roundup for a few weeks now and it is 
very good. But one particular issue (number 37) in the 
db has suddenly got a bit confused. A new message 
was added to this issue using web interface. The next 
time we did a "show all" we got a template error 
complaining that this issue 37 did not exist. I checked 
using roundup-admin and found that this issue has 
appeared to have lost its creator and creation date (but 
has everything else).

To fix this for now I have retired issue 37. 

Any ideas as to what caused this? Any way this be 
repaired rather than retired?

Thanks.
