Getting item requests late?

[yumpixels]

Sometimes when I log in, I will have item requests from my neighbors that are several days old. I play daily and always go through my feeds but this still happens. This actually happens with all of my story games. (RS, BS, FS, PS, not so much in DS) Does anyone else have this issue or is it something I'm doing wrong?

This seems to happen when neighbors send too many requests at once. Only 20 people can fill requests, so if they send requests to 40 people, the other 20 will receive them a different day.
