Celeste hasn't appeared on my island for nearly 5 weeks, her last visit was August 18th. I thought for sure she would visit today because there is a heavy shower however she is nowhere to be seen so I just ended up going to someone else's island to get the Virgo Harp recipe. Her not showing up for weeks is just RNG badluck I'm assuming, but I thought she is guaranteed to appear when there is a heavy shower... I guess not? Has anyone else experienced this?
