Oh yeah, that stuff is a pain and automated tests can only go so far. Also I know for me personally I do tend to neglect mobile a little just because I much prefer designing and developing for larger screens, and I doubt I’m the only one, so on mobile more will slip through the cracks when it comes to these tiny changes.
I bet Nintendo has a lot of patent violations to choose from. They have a patent on such bangers as, rephrased from legal speech to human speech: “An air mount automatically turning into a ground mount upon landing” Source
According to Nintendo, if I understand this correctly, they have the sole legal right to make a bird mount that can also sprint on the ground if needed, because that sure was a special idea.
