We all like having friends and in Farmandia friends are a must, but unfortunately, the game makers have placed a limit on how many friends we may have.
The limit for friends is 100. After 100, if you add a new friend, an old friend will disappear from your list. Old friends are removed from your list based on the order in which they joined CafeMom, not the order in which they became your friend or started playing Farmandia. Also, if the old friend has 100 or fewer friends, you will remain on their list of friends. This can create difficulties when sending gifts, so be alert!
If someone sends you a friend invite, but you have no more room on your friends' list, consider being courteous and tell them why you are not accepting their invite so that they won't be discouraged. You never know, you may need them as a friend for your farm some day.
