saving file previous location no longer remembered by High Sierra update
I'm using MacOS High Sierra 10.13.3
After a recent update, I've noticed that no matter what app I export, save, save as...etc OS will now default to the same folder every time, rather then remembering the last saved location. As an example, I export files from an app all the time. The old way it would recall the previous directory and I could then pick the same directory or one nearby...now it starts at a root level directory that is the same no matter what I'm doing and something that was once super quick and easy is now taking more time and annoying. Why??? How can this be fixed?
