There is a bug when calculating flow distances when two adjacent catchments are considered in the mesh but not nested. During calculation, a flag is set around the 8 adjacent cells of each upstream cell and not on the upstream cell in particular. As a result, a gauge stuck to a pixel of another catchment will not be considered as a non-nested gauge and will be filled with -99
