The activity Synced, but the Rank didnt. Is it supposed to be like that? He deleted all previous posts, so that his post count went down and the activity too. But does the rank stay at the highest you have achieved no matter how much activity you have lost?
There's the empirical answer to this coming either today or next tuesday or the one after that. Right? If no one really knows for sure, we'll find out soon enough.
The rank relies on the activity and should thus update with the activity. Activity is updated every 30 minutes IIRC.
