Bug: Dragging track to export window clears ALL playlists

Sorry, where are you dragging from / to?

The bug seems to trigger in two places, and is completely intermittent (I spent a good while dragging tracks around before the following happened):

1. Dragging a track from one playlist, into another

2. Dragging a track to change the play order in a single playlist

Please see the video (featuring total random dragging).  After a while, all of the playlists (which all contain multiple tracks), all show as empty:

Watching this back in slow-motion, it appears that the bug is caused when the playlist is changed, and during/before RekordBox has finished rendering a waveform.

My computer never used to render the waveform so slowly by the way - this only started happening around v5

We can't be friends - you only gave Maurice 4 stars.

Is that video realtime or was it sped-up?

I think my video converter software has sped it up.  If you select x0.25 playback speed on Youtube it looks more sensible.

I did a second capture this morning, although sadly the framerate seems trashed when I upload it.  This time, I am simply dragging the track order - it has nothing to do with rendering waveforms.

Two bizarre things happened:

1. Rekordbox prompted me that a playlist contained the track already, even though the playlist was only re-ordered - the track was not dragged to a different playlist

2. Again the playlist gets wiped (restarting Rekordbox loads tracks back into the playlist - it isn't a permanent deletion)
