other people are reporting having the same issue. Thing is, over a week ago, they intentionally reset the solo shuffle ratings on the beta realms. After that, people have come to the forum complaining about the same thing happening on the live realms. I’m thinking it might be connected somehow.
(Just to clarify, I don’t mean that the ratings got reset at the same time as it obviously didn’t when you read what their complaints are and when they wrote the complaints and the timelines they describe, as well as the OP in this thread. But the circumstances are suspicious, although it might just be a huge coincidence.)
