Casino gambeling and hyper prego teacher have missing png's.
For the school teacher make sure your files in img/characters are like this
$School Teacher.rpgmvp
$SchoolTeacher Hyper.rpgmvp
$SchoolTeacherhyper.rpgmvp
I forgot which one I put a space in for but make sure they all look like this proper spacing and proper capital letters this worked for me
still trying to figure out the casino thing
