The rain never stop, but the weather and daylight circle still work. So the undead mobs can still burn in the rain, but also the endless rain will consume my phone's performance.
It first appeared on the phone, then I moved the world's copy to the UWP version, the bug continues. On the UWP version, a reboot can fix this problem, but the rain in Android won't go disappear.
