Folders with periods failed to sync
I have all my music organised by artist as the first level of folders on my laptop. It's sync'd with Google Drive and then Astiga is sync'd with Google Drive. There were only two folders/artists that didn't appear in Astiga after the full sync completed: P.H.F and Run D.M.C. They are the only artist folders that have periods in the name. Also, when I removed the periods, so they're now named PHF and Run DMC, it sync'd fine.
It's a bit weird because in my "Beatles, The" folder I have an album subfolder called "Sgt. Pepper's Lonely Hearts Club Band" and that album has sync'd fine. So it only seems to fail when the top level folder has a period in it?
Not a big issue since I've solved it by renaming the folders ;-)
