How to make my bot do Nephalem and not greater rifts?

[DiabloRace]

So my bot is up and running but my barb starts doing solo lvl 59 greater rifts which are obviously impossible unless ur using unity and have a mercenary.

How do I edit the script so he just does Neph (Normal) rifts and not Greater rifts. I see there are ID's of 1 and 13 in the script. Anyone?
