In my list of neighbours who have gifted, more than half of the list can't be gifted back. the gift "button" which is dulled out says i have already gifted them that day (definitely have not).
Tried visiting but still no gift icon. Even tried looking for them from my neighbours list but then I can find them at all! Not had this problem previously. Played since November and this is recent thing. Tried closing games and reinstalling but has not helped.
