If you wait too long after your rise, it will "flatten" in the oven. My yeast rolls have done that.....so I immediately put in the oven after the second rise. Close the oven door carefully. Don't let anyone else slam doors after placing it in the oven and it has started cooking for a while. Make sure your often is at the maximum temp for the recipe before placing it in the oven.
Good Luck, nothing better than homemade bread!
