My Guild actually lost a lot of influence because of these bugs and Guild Missions bugging out. Mailed support twice about this and all they said is that they won't do anything about it and that I could make a Bug Report ingame. Totally not surprised with the response Matt got.
But you see, I am surprised, because I know what we can do in his case. I don't have the details of what you've experienced, but I do believe we can assist Matt, and we're ready to try to do so.
If you want to give your ticket numbers, I can review your situation, but it appears to be quite different than the one to which I responded, and the outcomes you received may very well have been entirely correct. In Matt's case, I think things have changed and maybe we can help!
