When I load up from the included file Herb and Mining 1-50 Durotar, Nothing happens and it just says "Moving to next hotspot". However, if I am close to the node it will automatically collect it but that's only if I manually move it there.
Durotar was redesigned when cata was introduced. Maybe those old hotspots are not on mesh anymore and HB can't navigate to them (as they could be below surface)
Looks like a flying profile, but you cannot fly. Hotspots are up to 100yards above your current position
