Hi, Josh.
Unfortunately, I don't have access to that particular account anymore, so I don't know if it's still happening. I've sent you the customer id, campaign ids, and date range via email previously. The rest of the info: this is for the keyword performance report, in GZIPPED_CSV format, with the fields AdGroupId, AdGroupName, AverageCpc, AveragePosition, CampaignId, CampaignName, Cost, Clicks, Impressions, Date, Id, KeywordMatchType, MaxCpc, KeywordText, AdNetworkType1, Device, QualityScore, Conversions, ConversionsManyPerClick, and TotalConvValue, with returnMoneyInMicros set to true, using v201309 of the API. We last ran this report Nov 19 and saw this then, but haven't run it since and, as I said, can't anymore at the moment. We probably ran the report 5 or 6 times that day, and saw it each time.
Thanks,
Greg
