Reply to Traktor 2.6 - scrubbing in flux mode suddenly makes track play backwards?

I just upgraded to Traktor 2.6 and started messing around with the new flux mode. Something odd has started happening though - if I have flux mode on, and then rapidly scrub backwards in the song (usually about 30-60 seconds), the song suddenly starts playing backwards. The play head still moves forwards, but the audio is playing backwards, and the waveform gets blurry. I have to re-load the song in the player to get it back to normal.

Has anyone else experienced this? Is this user error on my end, or is it a bug in the software?

Thanks.
