Lately, I've been trying to get serious about completing the art wing in my museum, but I keep getting the same artworks over and over. I usually prefer not to time travel, but after 450 hours where I couldn't get even half the art pieces, I decided to try the Redd exploit where you buy a piece of art and then reroll his daily pool by travelling to just before 5 am the day he's visiting. Here's the weird thing: I did as I was supposed to —and please, correct me if I did something wrong—; on the 27th, I went to the boat, I purchased one artwork, I saved and closed the game, I changed time to the 28th so I'd receive the artwork and then I changed it back to just before 5 am on the 27th so when the time hit Redd would appear with new art. Well, guess what. 5 am came and Isabelle told me in her morning announcement that Flick was visiting. And there he was. I even tried again and got Sahara. Did I do something wrong? I can't find anyone online who had this happen to them. Is it possible they fixed this so you couldn't reroll Redd in one of the latest updates?

EDIT: As u/slipstitch626 told me in the comments, it looks like the visitors for a given week are decided at 5am on Mondays, which is the case for the 27th. It would explain why I kept getting different ones. I'm keeping this up just in case someone finds themselves in the same situation and looks it up (it may sound stupid, but you never know).
