Set now includes a "fix" that adds Scan probes.
Use it at your own peril, but you can scan for scan probes using the directional button, which you cant without these groups on overview.
NB - this isnt a python injection thing or anything. The overview already gets this info from the server, its just ccp havent added them to overview.xml's yet which actually displays them - despite promises to do so to the csm. So all we have done is added them to the xml ourselves.
