What is this Patch doing?

Downloading 23 GB from 15,69 GB ?? Then go back to 9 GB and downloading again ?


Mine jumped back around the 12GB mark back to about 8.8GB

Then took three restarts of the sim before the mouse would interact with cockpit elements.
Some big issues introduced elsewhere too. If I said I am unhappy with this patch, that would be an understatement. 2hr+ this evening in the sim and not a split second spent in air. I love being a volunteer software tester lol
