If the file size has changed that much, than the document content was indeed lost, not just hidden, but that still doesn't help investigating. If you still have that 2 month old backup, please keep it, I'll try to find a solution on how to investigate, if you are willing to help with that. This is indeed a serious bug resulting in data loss, that should be fixed.
