Hello Miguel, this is indeed a very strange issue, I don't think that anyone here has seen anything like it before. It looks like you can access learning topics with your account if you jump directly to a URL (e.g. learn Sass), so if your concern is largely about making sure that you can continue to amass points and badges on the same profile, that is a potential albeit imperfect workaround. I've filed a ticket with our engineers to look into this but with yours as the only example of this sort of error, it is unclear when we may be able to pursue and implement a fix. At least you are able to access Codecademy through an alternate account! I'll post again if and when we learn anything more.
