I created a mesh by detaching it from other mesh, removed all doubles and tried to use loop select to add some bevel, but for some reason, it doesn't work at all. If I hold Alt and click - no additional faces or edges get selected, doesn't matter if I'm in face or edge mode. I also tried to loop-select through menu and it doesn't work at all, it simply deselects already selected face. It works though if I create a different mesh. Why is this happening? I'm on PC/Windows 10.
