As well as the great information on Matt's document, a recent addition to BIAB is also worth trying.
This is the "Auto-Fix Sour Notes" option.

To access this...

1. Right-click on the faulty track (the Bass track in your case).

2. Select "Track Settings".

3. Select "Auto-Fix Sour Notes".

4. Unfreeze your faulty track if it is frozen and regenerate the song so that the setting can do its job.

The image below may help explain things.
