I observed in the last 24 hours the following two bugs.
I did not get the usual red banner notification when the reputation count surpassed a privilege limit.
Also I by chance discovered a comment under a recent question, which was addressed in the standard way "@user" (without spelling-mistakes!) to me, but it did not show up in my "response list", nor did I get the usual red notification icon on top of the page.
Are others having the same bug?
