I am aware of the relatively small scale of my issue.
I contacted a GM in-game twice explaining my issue, and each time I received the same generic "we can't help you" response.
I am upset at the lack of attention and interest from GMs thus far and if this is a recurring bug I hope it does get resolved.

Thank you for your time.
