I don't know why but for whatever reason the counter for how many consecutive days I have visited music.stackexchange.com gets reset randomly even though I have been on the site those days.
Currently it shows 2/30 days for the Enthusiast badge and this is the third time this has happened already. I know that I can't prove anything but I am 100% sure that I have visited the site on the days that the counter gets reset on (even multiple times a day). Even when I don't spend a lot of time on the site I still visit it every day to make sure the counter keeps going.
It works completely fine on StackOverflow where I am on 83/100 days. Usually after every StackOverflow visit I also come here as well, so this definitely seems to be a bug.
