Levelup/Click Error

[Nieth]

Hey, sometime when we click pets to give them clicks, or just just try to level them up we get an error. I tried reading into it and going to the areas where it specified that they were, but I couldn't find anything obvious, since I'm not really a coder. Someone please take a look;

Also, when trying to open mail from SYSTEM, it states that it is not a user and you cannot open it;
