Greetings Inzoum,

We appreciate you taking the time to report this trouble you are having to us. However, since this sounds like something requiring an in-game GM support rather than a bug report, I will be closing this particular thread. We welcome you to file a GM ticket in order to seek a resolution. Thank you!
