I was looking up and issue and someone fixed it im going to copy and paste and try it from there!(
As I’m certain that someone else has said this prior in this thread but here’s the solution to any missing image error you get so when the game fails to load any image you just have to make a new file for it, just go into the folder that its looking in ie img/characters find a file with a similar name [like cowgirlyellowbust2] make a copy of it and rename it to match what the error message says
So it looks like you got the error failed to find img/characters/$Cowgirl Yellow Bust3 just go to that folder and make a copy of any cowgirl yellow bust3 and rename the copy to match what the error is looking for)
