mincut analysis returns all feratures giswater 2.1.x about giswater HOT 4 CLOSED

Dear Taylor,
It's a bug of 2.1 version, Sometimes the construction of polygon it's done with multi approach. It was not easy to fix it. I thing the best solution is comment the lines of gw_fct_mincut function from114-127:

-- Contruct concave hull for included lines
polygon_aux := ST_Multi(ST_ConcaveHull(ST_Collect(ARRAY(SELECT the_geom FROM anl_mincut_arc)), 0.80));
-- Concave hull for not included lines
polygon_aux2 := ST_Multi(ST_Buffer(ST_Collect(ARRAY(SELECT the_geom FROM v_anl_arc WHERE arc_id NOT IN (SELECT a.arc_id FROM anl_mincut_arc AS a) AND ST_Intersects(the_geom, polygon_aux))), 1, 'join=mitre mitre_limit=1.0'));
--RAISE EXCEPTION 'Polygon = %', polygon_aux2;
-- Substract
IF polygon_aux2 IS NOT NULL THEN
polygon_aux := ST_Multi(ST_Difference(polygon_aux, polygon_aux2));
ELSE
polygon_aux := polygon_aux;
END IF;

I encourage you to use the 3.1 version. We don't provide support for 2.x version
3.x version will be supported and updated next 2 years at least.

Oh, I rolled back to giswater 2 because I thought it was easier to work with where it didn't ask for as much information and there was less required fields and domains.
I will try what you suggest and then try to go up to giswater 3.
