I am a beginner and have no idea what I am doing, so I don't know if this is a bug or a user error. I copied the robot player and then remodelled it to use in my game and it worked fine but after I had saved the game, exited and then opened it again whenever I played it constantly made this weird noise that sounded like it was broken. I deleted my character and put in the robot instead and the noise went away. If this isn't a bug, how can I fix it, and if it is how can I work around it?
