Transients won’t show up? Check for duplicates!

If you’ve found that particular transients simply will not display in your theme yet they aren’t throwing an error?  Check your database for duplicate entries.  It is possible when moving a site between servers for a transients to become duplicated within the wp_sitemeta table and this causes the get_site_transient() function to silently fail.  Simply go in and remove the duplicate transient ‘meta_key’s that are LOWER than the highest duplicate.  After doing this you should now see your transients correctly.
