Greyed out on the partylist. What does it mean?

Dear Nanobit. The real problem is that my friends all of a sudden is greyed out on the list. I thought my good superstar life friend mariannesoriano67 deleted me, because she was jealous and we got into a fight about it, but she says she did not delete me at all. Why is some greyed out on the partylist all of a sudden. can you answer this? The problem especially appeared since the last update.
