The first and second is the acid being built. The third picture is the acid after it has finished building. The fourth picture is another acid at the same room being built. The glitch only occurs when the acid is building and it becomes normal when finished. Also, I think the glitch occurs when the wall they are being built on is slightly at an angle, or next to a wall that has slight angle. So far I was able to reproduce the glitch only when the wall has a slight compound angle.
