Hmm, it is not a Monday. You have a fair amount of "Points This Week." I do not understand why you would have lost it.
Did you stop answering in what you were a 'TC' in? Keep in mind, you must continue answering questions in what category you are a Top Contributor in, and get a 12% Best Answer of those questions. Answer 20-40 questions a month and get a 12% Best Answer to keep it. However, maybe you never really had it, could have just been a glitch when you got it. Other theory might be, it might just be a glitch now, and maybe 5 or so minutes later it will come back on.
Hope everything turns out good with you and your badge!
