Usually I send the same gift to all my nbr.
Today, I plan to sent different gift to each nbr, and leave a note on the wall, hoping to get different gifts from them.
So, I go to the nbr list, visit the 1st nbr, send ONE gift to THIS nbr, leave note.
Return to nbr list, visit the 2nd nbr, send ONE gift to THIS nbr, leave note.
Return to nbr list, visit the 3rd nbr, send ONE gift to THIS nbr, leave note.

Retrun to nbr list, and find out all other nbrs' "gift" icon were darken. Saying I have reached the daily limit of send gift.

Only 3 different gift per day??!!

OR THIS IS A BUG?

Can anyone tell me?
