When I was modeling a sofa the other day, I collapsed one of the meshes which has a Turbosmooth modifier in Isoline Display. In fact, I didn't notice until this time that there is a bug and I didn't even notice the buggy result at that moment. Probably I was in edge mode and when I noticed the outcome pretty later that it was too late to undo.

The image above shows the problem. As you can see, the new edge loops are not there but only the vertices.
It is a very easy fix with a simple box model, but I had a complex mesh which was really hard to fix and which would take a lot of time.
I was very lucky to find this script which saved my day:

Vertex Killer by Mauricio B. Gehling

This tool will remove any SELECTED vertices that are shared by ONLY and EXACTLY 2 edges. Thought it might be very useful for someone who collapses the Turbosmooth in isoline display.
