You mean the walking sprite? While there are cutscene art for each of the 10 stages, there are only about 5 stages of walking sprites. Plus, some of those walking sprites are reserved for the later game where med bay procedures can increase the MC's max on the blue meter even further. The sprites between WG and P are a little different. If you're still having trouble, let me know on the discord server. I have bug reporting channels dedicated to tracking issues there.
