The achievements dropdown is not showing all the rep I earned:
The question was asked and answered today. I have not hit the rep cap. I have never seen caching be an issue in the dropdown before. I first noticed when the question was accepted - I saw it on the main page as accepted, but I had no rep gain from that, so assumed someone else's answer was accepted. While I was loading the page, my profile, the page and so on, another upvote came in. Yet through these events the dropdown continued to just say +10. Even when the tag badge appeared, the rep change stayed the same.
