I definitely think that there is an issue with the "Albums Edited" entry in Stats.

On 45cat if you 'Add Missing Info" or "Make a Correction" the count in the "Records Edited" box goes up instantly.
On Vinyl Albums it never goes up. I've just had a look at "Albums Edited" scores of active members and I couldn't find a single member with a score, everyone (including mods and admin) has a score of zero.
