I've been monitoring the new release thread and noticed that a few people have been getting a message saying that they couldn't work certain "friends" facilities because they "weren't friends". I haven't had a problem with this until today.
Facebook made some changes to the feed in the last day or so and I took a closer look at the links I was hitting. I realized that what I was clicking on was not a facility link from my friend, but a facility link from one of their friends that had been reposted because they had "liked" the link. The new font that FB is using makes this a little more difficult to recognize.
This may not be the entire reason people are getting this message, but it is certainly the reason I am getting it. I just need to look at the post a little closer.
