Been getting the message for the last week, that I cannot send any more invites today. (when selecting "Friends Playing Zombie Slayer") Then, the selectable friends disappear from the list. I'm hoping that the invites are being sent, but my squad doesn't seem to increase and assuming (hoping more likely) that at least person has said yes. Did a search but couldn't find this reported. Seems very much like a similar issue zynga had with the truly horrible Street Racing game. I'm hoping it's not...as they never really fixed that meaning if you were unlucky enough to hit this bug, you basically got stuck where you were in team size forever, couldn't send/accept gifts, etc. So...is it just me, or has this been reported?
