Dear all,

I am running a least cost path analysis combining r.cost and r.drain.
But on some cases, when the least cost path between source and target
reach the border of my map, r.drain stop on that position, and target
point isn´t reached. Running on other softwares the algorithms the
source and target is connected using edges without problem.

Any hint are welcome.

Merry Xmas
