I read that they were also invisible to one another, two players were streaming on the same location but neither of them could see the other

There's also a whole issue going on with the European limited edition box, originally it was printed with stickers for an age rating of 12 and to include multiplayer, but another set of stickers was replaced overtop of it with an age rating of 7 and no multiplayer (peeling it off will reveal the other stickers)
