I'm creating a playlist and found that after I've re-arranged the tracks in the playlist (and saved the results) the order of tracks was restored back after some time. After the re-arranged the initial page refreshes were showing the new order. After some time however (and after several new tracks added), the order has randomly rolled back.
This happened to me twice today. Being the programmer, I'd say its a client data loss - very unprofessional. Not that I'm paying monthly subscription though, so don't take it too serious.
The playlist url is https://soundcloud.com/nickolay-platonov/sets/cijam
Hope to see this fixed, and may be add to the roadmap to add the drag-n-drop support for the main playlist screen?
