Drill-O-Matic issues

[Bigbootie]

Does anyone know how to correct this or see something obvious in the attached screen that I am missing?

I have this drilling rig and it has worked fine for many, many mission. Now for some reason it will not drill  at a reasonable rate at all. Used to fill a tank in no time(less than a day or so) now it would take years. I even slapped on some more radiator panels to try and help, Is this a bug? The one thing that has changed is that I used to use only the drilling rig and attach it with KAS/KIS directly to my refueler rig. The large rover that is attached in the screens is new. However, when I unattach it still does this. I even tried reattaching the old way, still the same. I then moved to a new ore location about 3km away and tried with drilling rig only. Still the same.
