Updating CC desktop app changed location of CC files

Hi, I recently updated the CC desktop app, it would seem yesterday, according to the desktop app itself. Unbeknownst to me, this update reverted the location of my Creative Cloud Files folder, from where I'd set it on my 6TB RAID5 Data HD array, back to the default of C:\Users\Brian A\ on my 500GB SSD system drive. It perturbs me, both that this would happen at all - an update should not change or clear user preferences - and that there was zero notification that this had occurred. If at some point my system drive approaches full between apps and app data, having something like this occur could cause a very large mess. In fact, less than one month ago, the C: drive on my last computer would not have had enough space. I'd no clue this had even happened until I opened preferences in my CC desktop app and noticed under Files, my location began with C:.

Was this a bug? Should I report this somewhere? Is there a way to prevent this from occurring with future updates?

Thank you in advance for your time and knowledge.
