**System Information** Operating system: Linux Graphics card: GTX 1070 **Blender Version** Broken: 2.80 Worked: - **Short description of error** If used in the correct/wrong way, the dissolve vert function can create duplicate faces **Exact steps for others to reproduce the error** Based on the default startup: 1. add a Tetrahedron in your favorite way (for example a cone with 3 segments and filled base plate) 2. dissolve one edge of the tetrahedron with X->Dissolve Edges and F6->Dissolve Verts=0 so the vertices stay the same 3. dissolve one of the vertices that now only have 2 adjacent edges with X->Dissolve Vertices you should be left with a duplicate triangle with normals pointing in different directions.
