Saves not backing up to the cloud on Xbox One BTU

Found a issue with cloud saving in the Better Together update. I went to use my new console and my cloud saves are about a month old and my local save is corrupt. I think the issue is that as the file size gets large it doesn't upload it to the cloud. I did lots of exploring and that created a large game size. The saves that do upload to the cloud are smaller in size. You guys need to address this, this is definitely a bug on the Xbox One.
