It wasn't Clarr Solo. I forget exactly who it was, but it wasn't Clarr. I could probably find out with a little looking, but I'm lazy.
The NavComp draws information directly from the Dev DB, not the one here on Main, and so displays systems from over there we don't have here, and doesn't display systems that have been added here more recently.
There is a bug report about it, I'm pretty sure, and someone will get to looking at it eventually.
I suspect the reason it was linked to Dev was something about it showing Hidden systems from here on Main.
