Strange Facebook issue

Hello,

I gave one of my customers 500 likes.
After I did this he had 800 likes but sometimes his facebook page changes to 73 likes and you will see his old profile pic. and old posts.
His new posts dissapear...

Anybody has any experience with this?

Facebook bugs with all the changes they are rolling out is inevitable

It is still happening with my customers page. Anyone else know anything about this?
