I just checked, and there indeed was a small mistake, which is that when you train, you gain experience, and when you reach a certain amount of experience, you move up to a new level of physical strength. So the mistake was that you only move to a new level during physical training, but now you can move to a new level when hitting the wall as well. As for now, we can suggest you to do physical training for a few days until Sarah says she is stronger, and then to work on the hole in the wall. Thank you helping make our game better!
