Ghost of Tsushima sales are exceeding expectations in Japan and the game is facing a stock shortage, Says PlayStation Japan

Not talking about "issues" per se, but rather a distinct lack of polish. I wrote about this in this week's Weekly Discussion thread:

There's a certain amount of jank here that I didn't really expect from a first party Sony title. It doesn't make it a bad game, but it does prevent it from reaching the level of quality that I've come to expect from their other studios. The camera isn't great, the bird that guides you to points of interest will happily fly directly into solid objects like buildings and rock walls, most foliage doesn't bend or react at all when you walk into it (it'll just pass right through your character like he's a ghost), and so on.
