What you do:
• Create a V-Vocal clip and make some obvious edits in V-Vocal
• Freeze the track with this clip
• Unfreeze the track
• Press play

What you expect:
• V-Vocal renders the same as before freeze

What happens:
• V-Vocal now time moves, but V-Vocal processing is not applied.

How to work around it:
• You must do a "Remove V-Vocal" and then undo to get the V-Vocal clip to work correctly, even after save and reload.
