Removing sound files from a sound set does not appear to work properly in any circumstance. This bug seems to be present from version 0.1 right up to 0.4.
Steps to reproduce:
Load a .bcsar and click 'Sound sets'
Right-click any sound set and click 'Edit contents'
Click any sound file and then the '-' icon
Click 'Commit'
Right-click the same sound set and click 'Edit contents'
The contents of the sound set will not have changed. This will also be true if you save and reload the .bcsar.
