In two-player games, when one player goes into an inventory/crafting menu, the pointer flickers for the other player.
In four-player games, when one or more players go into an inventory/crafting menu, the pointer can disappear completely for the other players. In this case, any activity requiring crosshair activation (such as opening a chest) cannot be performed.
