I'm getting this notification: "Congrats, you've gained the privilege – talk in chat and 2 other privileges learn more." However, I only have 11 reputation and I cannot talk in chat since this requires 20.
Checking "show removed posts" does not show any downvotes but even if this was the case I would not expect to get the notification. Note that if i remove the notification (click on the X) and click again on my username I get the notification again.
Is this a bug?
