I know how to get around the bug!!

I loved falling asleep to this app. Hated when the sleep timer stopped working. This is how you get around the problem. Go into your clock and choose the timer feature. Scroll to the bottom and select "stop playing" choose how long you want your sleep timer for and go to sleep. It WILL turn off the koi pond when the timer is finished.
