One of my buddies never shows when they are offline, like when I visit their place or if they come to mine, they are not on my list when I come to send chests, anyone know why this might be? It has only happened one time before this, everyone else is on the list..

Hello CareneLeFay

My Buddy List is "Special" too : the Buddy List from the Free Gifts Tab used to send chests and the Buddy List showed in game are different...
Buddies in the game are right but from the Tab, i can send chests to ppl gone for years.

About your issue, i know that ppl who use the Rooms got from the GE challenges and set one of them as Main Home are invisible when you visit them.

Hey there Butterfly <3 That is interesting, But this buddy uses their apartment as a default room. Only once before it happened, when I realized a buddy was not using their main Facebook to play the game, and it was resolved once they had added me on Facebook. This cannot be the case here as I have no Facebook connection to this person .Its no biggie, just strange.
Thankyou for your thoughts x
