OMG! Thas has been happening to me a lot today! I was like wtf! Lol! It was so weird! I think it is technical difficulties which they seem to have a lot of! If te Refresh o Click On Your profilo It Should Help To See Updates!
It's done that to me a few times too. But it only did it when I let my friend sign into her account on my computer. After she was finished on her account I signed back into mine and looked at my profilo for some aggiornamenti and it had the club i had in common with myself...
So I think it might be related to signing into different accounts maybe?? Because the club in common thing only happens to users other than yourself te know?? yeah..
Try signing off and then in again. Hopefully that works. fanpop fix it!!
