## Summary When a server is deleted, we now update the identifiers of any locally-defined actions or complications to point to the first server. We want to avoid ever having a server identifier pointing to a deleted server so we can trust the identifiers more. ## Any other notes Deleting in this case would be bad as it's an unexpected data loss. I can imagine someone deletes and re-adds the server (potentially the last one, too), or other maintenance tasks.
