Be it Finding the way Home, dragging Corpses to their Graves or getting Resources, if this is Intended you might want to add something to at least show the range possible ? I tried using Torches as waypoints but that didn’t work, i also had a Road build all the way out, that actually seemed to help them at least to find back Home. Also, since you have to build the Graves in reach (whatever that is) to the Corpses, it’s a bit weird to drag around a Grave to your Graveyard but that might just be me. 
You got us there. Distance really is a problem as we want to avoid your colonists wandering off too close to Tikigoblins. We’ll address this problem with our next update. Sadly we can’t solve that for Alpha 7 which will be released this friday.
