I took over 12 hours to get the 15, I woke to find I needed 2, I even added a few more requests before s8 new day started, guess what, I got 5 shortly after the new day started. I sent out 20 to players I know have sent back requests quickly or send gifts / visit almost daily etc. Including Stormie. Thankfully the 12 hours went over most of my sleep time so I wasn't sitting screaming at the phone.
