I am not sure when it happened, but I went to do proportional editing and the guide-circle that indicates how large an area is being affected, had disappeared. At first i though it was perhaps very large suddenly but I scrolled out and it was not there. When I select one vertex with soft select enabled it will just move the whole mesh, now. Did I accidentally click the wrong thing, or could this be a glitch because my hard drive is in the red zone (getting full) ? I restarted my PC but the problem remained. Could i solve the problem by reinstalling Blender?
I opened another smaller file and the soft select circle is there! So this problem only applies to this one project file.
Thank you for any help!!!
