OK, I am having a hard time trying to explain this, but I will try.
 
I am hearing reverb on vocal tracks, from a mix I did the other day.  I don't have any selected reverb on the PRO Channel so I am sure the reverb it not coming from there. 
 
I am routing the vocals to an effects bus called effects, and it outputs to a channel called Vocals,  vocals goes to master.  I am pretty sure I had added a VC-64 (32 bit) effect on the effects channel using a preset that I had save which also had a Lexicon reverb, compressor, and an exciter, but it does not show up there.  But, I am sure it did before.  The odd thing is that I can hear the reverb, but if I route the vocal directly to master instead of effects the reverb goes away. 
 
The VC-64 (32) bit still shows up as an option to add under audio FX, and I can drag it into the channel.  Also I can add the present which has all 4 of the effects that I use.  It just doesn't seem to show up on the channel where I put it a few days ago, but I can hear it.  Has anyone seen this or have any idea what is going on with this?
 
Thanks

Have you looked in Console View? Be sure the FX bins are visible, and can check all tracks/busses quickly that way.

Click on each of the busses in turn and look at
1) what is in the FX bin, and
2) what effects are in the ProChannel.

Thanks for the input everyone.  I was able to finally figure it out.  I was sending the vocals to the effects bus, but I had forgotten that I was using a pro Channel on the effects channel.  I was just cashing my tail.  Thanks for helping!

Your tail its with cash? Totally jealous!
