Remember though, starting over is essential, it is always a great choice to start over. When a mesh is a mess, cleaning it or trying to get the loops to flow another way or cleaning it or breaking stuff apart to redo, it’s always a waste of time and starting over is the best choice, not only is it faster but you learn a lot more, you learn of ways to not go about a mesh, you gain speed, etc.
As Jaanus says, most likely snapping is on.
