The morphs group which wouldn't die [Edit]

second_technician_rimmer_9571136c47

A while back, I tried to recreate in G8F a group of several morphs initially made for G3F and I managed to convert these shapes just fine. Somehow, later in the process, I had these morphs committed to G8F with the Morph Assets function. They appeared as a group we'll call "first-attempt". The "first-attempt" group was visible on the parameter pane when I would load my G8F (and G8.1F too somehow). That was fine. 

Later on, I managed to create better morphs. I deleted the "first-attempt" morphs from my drive (and I really combed it to be sure). I tried to inject the new group "second-attempt" and these, remember, are a modified version of the first batch. And this is where it goes wrong: both groups now appear. If I delete my new batch of morphs they also both disappear.

How can I prevent the first group from coming back?

A lesson well learnt: always check the morph file for name errors in the folder label.
