Been waiting Challice now for few days. They must have changed something, because Chenori who sells the tailoring stuff is standing exactly where Challice used to be, atleast according to old screenshots and vids like: https://www.youtube.com/watch?v=Ccf02lN_6H4
So no Challice and Chenori standing in corner where Challice should spawn. It's pretty clear though that Chenori is not PH and they can be up at the same time.
Something fishy is going on with this...
