Level up glitch

[JayGatsby]

Hello, I am currently using your free script. (It's great, by the way. I really like it) However, I am getting this weird error. You can refresh on some adoptables and they can get leveled by the same person infinitely. Also, it says the level is maxed out even though I have images for the next level. It still grows if you get enough clicks though. Does anyone know what might be the problem?

Here is the URL to my site if you need it: http://www.area31.comze.com/

Thanks a bunch in advance.
