I'm not sure if anyone else has had these errors come across, but this is the 2nd one I've got in 2 months.

  Database error in vBulletin 4.2.0:
   
  Invalid SQL:
  SHOW CREATE TABLE `vb_taggregate_temp_1339494960`;
   
  MySQL Error   : Table 'vb_taggregate_temp_1339494960' doesn't exist

I've searched plugins and can't find anything relating to this error, and I've also searched files with nothing relating to this error.

Any ideas?
