I have noticed this bug in LEGO® Answers where my badges don't show in the list of Accounts I have in StackOverflow and other StackExchange Accounts. I have earned about 8 badges and none show up.
Edit: The "Badge Bug" has been fixed.
Curious - they are appearing on your overall Network profile:
Could possibly be a slight caching issue - when did you earn those badges? If it's fairly recently that might explain it.
If it's not cleared up in a couple of hours I guess we should escalate it further.
Following it further, I can see that your Ask Different badge count has increased across the network (it's now 3) - I've raised this on meta.SO, it may be closed as a duplicate.
Looks like there's a more systemic issue - I've just noticed that a lot of our users are missing a large number of badges in the summary.
Edit to add:
It's been fixed, thanks for raising it :-)
