I play the game on the ps4, I don't know if it makes any difference , the first day I play the game it worked fine. But now the upgrade menu won't appear. If I make a new save file it will pop up again, but when I shut it off and come back the next day, it goes away again! Also, when another player joins, the man gets all stupid and doesn't work. That's all I've seen so far, otherwise I love the game!
