I think you're being too hard on yourself! What you've done is incredible, it's only natural that there are a few bugs here and there, but it doesn't take anything away from the beautiful story you're telling.
I'm not even close to finished yet and it's already been such a wonderful experience, having a couple issues hasn't changed that at all. I'm grateful you're being so thoughtful, you definitely deserve some grace too after all the work you've put into this novel for us.
