A few days ago my OpenID was merged with another OpenID I had. Before the merge I had the
Woot! badge (now called Enthusiast), and now I no longer have it.
I would like to know why it was removed?
As others have pointed out, this was an issue with your accounts being merged - a fix for the merge process will be deployed tonight.
Your user history data has been restored and the "Enthusiast" badge will be awarded when our badge task runs again.
Also, badges are rarely removed once gained.
You ought to email the Stack Overflow team at firstname.lastname@example.org with your OpenID and they can take a look for you.
