The last couple of days I've had the process of making Spiral shells and Freshwater coral in Serenity falls mixed up - it requires Charsnips to make Spiral shells and Skyfruit to make Freshwater coral, instead of the reverse as earlier. The times are switched too, so it takes 1 min to make Spiral shells and 2.30 to make Freshwater coral. Not that it makes that much of a difference, but I just wanted to point it out, in case anyone else is experiencing the same thing. I'm on iOS, the latest version of both the OS and game.
