When I go to hover over the 4 rightmost inventory slots on the top row, it won't let me select anything. I can select while in a chest, but not while in my inventory or in a crafting table. This is currently happening on my friend's realm, but no one else has had this issue. Re-logging didn't fix it. This means I can't access these inventory slots unless in a chest. This does not happen on singleplayer worlds, or on servers, just on the realm. The game isn't unplayable, just rather annoying.
