Build 1832 - yep seeing the same.
- Opened song with no Regions
- Hit Play button and created 3 regions with spaces between them
- Stopped playback
- As soon as I tapped on the first region to select it I got that error
@peter - Possibly a regression introduced in 1832 where we fixed the problem of Waveform not being created if not all audio files are the same length?
