Yeah, that happens. For me it usually happens with the teachers, like trying to make them not take me down when I do something wrong. I don't know how you got it to happen with a regular student though. Just always be careful when editing the JSON. The process I learned through was just like making mistakes and then learning over and over. I think that editing hairstyles for regular students is perfectly fine, but it can get weird. If you put a boy hair for a girl I think they'll just be bald. If you put a color that isn't in the game or something their face and hair turns white. If you don't spell something properly, like "Ponytail" instead of "PonyTail" then, from what I saw in an old build, you won't get the tail and only a short head of hair. I don't know what happens in more recent builds.

Despite all of this, if you can get it right then the rewards are great. Adding your own OCs, making people go where you want to go (or close enough, at least), and other stuff can really help.
