Symptoms

In Sharepoint 2010, when attempting to update a managed metadata column after it has been renamed, the following error occurs:

Error occurred trying to Execute (SmoSPListItem) - Microsoft.Sharepoint.Client.ServerException: Column 'RenamedColumn_0' does not exist. It may have been deleted by another user.

at Microsoft.Sharepoint.Client.ClientRequest.ProcessResponse()
at SourceCode.Sharepoint.Client.ListBaseFunctions.getFieldByTitleOrInternalName(List list, String titleOrInternalName)
 

Diagnoses

This issue was identified and logged as a bug to be addressed in a future update.
 

Resolution

The only workaround available at this time is to rename this column back to what it originally was.
