And pigs can fly....

Microsoft can only upload the files that they receive by Bethesda and if there was a failure while uploading by MS they would have changed that allready. But thats only possible if they get working files.
Ive already had "bad data" from LIVE because of a failed upload for Arcade titles. MS staff are human and make mistakes. Mistakes take time to find, diagnose and rectify. It doesnt happen in minutes, its days of work on the LIVE network due to MS policy on uploads and the release dates for content.
When Bethesda is at fault for major problems I will, the same as any right minded person, blame those at Bethesda for the problem. But I wont blame someone for another persons mistake, because thats out of order.
