Dough gets punched flat on purpose, then rises higher. Getting knocked down is part of some recipes.

Some processes require a collapse as one of the steps. Knocking a thing flat redistributes what is inside it, which is why the next rise goes higher than the first, and that makes the setback part of the recipe rather than damage to it. Nobody enjoys the flattening. It still belongs in the sequence.

When something you built gets pushed down, ask whether this is the end of the process or the middle of it. Give yourself the rest the next rise will need. Then begin again with what you now know about the dough.
