Not entirely sure. The reason the AP goes negative is specifically because of a missing link between the UI and the method I called. I have already attempted a few things towards gems, but it did not stick, so I moved on for now.
I do not make private servers personally. This task resides in the grey area, to my understanding regarding laws, and I'm not much of a server data collector anyways. Too annoying to work with for little reward lol.
I don't keep up with updates of any such until a comment is placed for free public releases, so I do not know sorry. Whoever put up the server may be experiencing issues or may even shut it down. Hope for the best ahah.
