Bounce to Track - When?

Was working in Sonar X1, had a vocal track with clips split into smaller sections to apply V-Vocal on.  Once I had the track/clips set, should I have 'bounced to track'?
 
I left the track as is, and then cloned it, applied some effects to the clone to experiment.  Now, when I deleted the cloned track, the timing of the parent track was off from other instrument tracks by several beats.  I had never edited the original.  I ended up loading the last back-up copy of the project.
 
Anyway, how do the experts typically ensure a track won't change?  Bounce to new track, freeze...?
 
And when you 'bounce to track', do all of the Fx settings/outputs that were applied to the original track get saved in the new track?  For example, if the original track had a reverb plug-in applied, the new track audio will have reverb applied, but it's automatically embedded in the audio wave, there won't be a reverb Fx in the new track?  And how about the V-Vocal layers in original track?  Do they disappear in the new track?  Hope that makes sense.
 
Thanks.

I never bother with any of that.

If I don't want a track to change, I just lock it for contents & position.

I've never had the need to bounce V-Vocal clips either, though of course YMMV: many users have had to freeze VV due to hardware limitations/configuration.
