+summary: "Fix auditor error handling when updating non-existing record"
+description: |
+  It can happen that a drone is submitted but never reaches the AvailableState, since demand for resources is decreasing
+  and the drone is cleaned-up before and it reaches DownState. This case is currently not handled correctly in the 
+  auditor plugin, since it tries to update a non-existing record.
