Hi,
This morning was awful : All my users contacted me because their filters don't work anymore.
Each concerned filters was using " ... AND Account = 'FeaturesXXX' " to filter issues on a specific TEMPO account.
After i checked, the Tempo Custom field "Account" that we used for 3 years just disappeared to be renamed "Compte" ("Account" in french). The custom field is locked (managed by tempo directly) and i cannot rename it back.
Any idea about the cause of this bug or how to correct it ?
Thanks ! 
Philippe
