I have the same problem as svlyn2 and cinsinn - as far as I can see it applies to the number of followers, shared items and favorites on some of (mainly older) shared items.
My number of followers jumped by about 40, the number of shared items by about 50.
The counter of favorites on some of the shared items appeares to be multiplied. As an extreme example, I have a Maxis faved item which had around 1000 favs. All of a sudden it shows about 5000. Meanwhile the number of downloads seems to be on the same level.
Also I noticed the same issue with other users/creations throughout the gallery.
