I have a system that uses r.contour to trace reservoirs for hydroelectric plants and that problem is breaking my algorithm. In the attached GRASS project, you can see the result generated by different GRASS versions (contour level = 229) - look at the largest contour line. I tested the following versions: 7.2.3, 7.4.4, 7.6 and 7.7svn. Only 7.2.3 produced a continuous/unbroken contour." defect closed normal 7.6.2 Raster unspecified fixed r.contour x86-64 MSWindows
