I totally understand that your snake has escaped. I had a big normal male that escaped twice on me when I kept him in a tank. I then changed over to tubs and he never escaped again. I have two girls now that are in tubs and I have zero issues with escapes anymore. I'm not saying that you have to switch to tubs you DO need to make sure to do the right thing so that Monty doesn't keep escaping or she could end up getting hurt or worse.
