We're trying to run a migration and encountered this error, which doesn't seem helpful. Can somebody encounter this error?

Unhandled exception. System.ArgumentException: Column 'Saved' does not belong to table Table.
   at System.Data.DataRow.GetDataColumn(String columnName)
   at System.Data.DataRow.get_Item(String columnName)
   at EPiServer.DataAccess.Internal.PropertyDefinitionDB.CreatePageDefinitionFromDataRow(DataSet ds, DataRow row)

   at EPiServer.DataAbstraction.Internal.DefaultContentTypeRepository.MergeModelAndProperties(ContentType clone)
   at EPiServer.DataAbstraction.Internal.DefaultContentTypeRepository.EnsureMergedInstance(ContentType contentType)

It would be really much appreciated if someone could provide some answers.
