Not rewarded Silver for featured thread visits

So I've been busy for a week or two (maybe even three) so I haven't been reading new feature threads. Now that I got to read one, I noticed that I didn't get a notification telling me that I got new Silver. That was the first thing I notice every week when I first login in a week and read stuff. I look at the rewards an it was at least 2 weeks since I've been awarded for reading featured threads. What gives?
