I've changed today my email to one, which was associated with an account I used before this one and some strange things have happened. The both accounts somehow got merged with a weird result, eg. points on different forums added up, the length of my account here got extended by 8 months, all my tag points here disappeared. This is somehow unexpected... To make things complicated, I was "cleaning up" my different accounts around SE or rather removing all but U&L. Then I changed the email... In the effect I had to remove some of them again. These extra details might help you in tracing back the root cause if you do. This is not really a question, I guess.
Different badges are coming back slowly. Maybe the tags will come back at the day break or whenever they're counted up?
