Just noticed this last night. The little ❤️ on pet profiles appears broken on Chrome. On Chrome the heart appears black (I changed the color on a good number of my profiles) and when you click on it, nothing happens. The heart also seems to have been moved on Chrome on some of my profiles even though I have not touched my profile coding in weeks. I used another browser (Pale Moon) to check the pages and the heart button is in the place I remember putting it, right color, and can be clicked on just fine. This seems to be only a Chrome issue.
I asked a friend and she said most of her pet profiles did not have this problem but a couple did so I'm wondering it it's broken for anyone else also? x_x
[edit]
Just checked again now and it seems to be fixed! Woot! :)
