Unless I've missed it somewheee we still have no explanation as to what kind of bug/exploit could have been so awful that we have had so much downtime and even needed a rollback. A lot of people lost a lot of progress im the rollback, and we for some reason have no explanation for it? I think we at least deserve that much.
Just to let everyone know what happened, we had an issue with our backend infrastructure, but was able to resolve it and also determined why it became an issue in the first place. Thanks so much for your patience overnight!
