How do I make cuts properly?

sometimes when I try to cut the mesh, the software highlights some weird patterns and I do not know how to go back or tell it to make a proper cut. Can somebody help? I will try to describe it better if I can with a picture.

We are in the process of improving the infrastructure for cutting with a better algorithm for cutting. In the future the overall process should be smoother. Please always make sure that the cuts do not go over other cuts, that will not work.

In this specific case the algorithm is not able to find a path to the point you want to select. Probably the previous point in the cut path is on a different part without connections to current point. If you want to change last point picked you can always undo with Ctrl+Z (or Command+Z for Apple users).
