I added you plus 4 other ppl last night. I sent everyone a request for the diamonds, I did get two back, so it is going to some nbrs, but not others.
I have been fine, since yesterday. I sent a request to just my two other games last night, but it went to all my nbrs again.
Yesterday was the first day I have sent regular gifts to my nbrs (shoes, red sweater,) in about 4 days, and I then had issues again with my requests going, but that should not apply to you, since I just added you ,then immediately sent you the request.
