I was going to say the same thing, you have to start over from the beginning. It is counter intuitive but trust us, the way to move forward is to go back. When you have a mesh that is beyond saying, you are going to spend triple the time trying to fix it and you’ll just get frustrated. Starting over will allow you to get to the point you were faster and you’ll gain insights and speed, your brain will start to understand where not to go before you even know it, it’s like you’ll start to see the path before you have taken the first step. So yes, starting over is the best option.
