I logged onto my facebook yesterday (and today) to play this game for a bit and I noticed that the list for "Friends Playing Zombie Slayer" didn't change from the list of "All Friends". Majority of my friends on facebook do not play this game, so I know this must be a glitch or something. For me it's very difficult, let alone time consuming, to send gifts and invite new people to my squad when I have to hunt down all the names of the new people who added me and match it to the names on the list. Is this a "universal" glitch or is it just on my account?
