Recently I've started DMing a premade campaign (Curse of Strahd) for 4 players and I'm having issues keeping them along the pre-made questline.
I've been playing an official campaign to practice being a better DM but its very hard to rein the players to follow the questline because they continually get distracted. They are having issues following the questline because they don't seem to see the big hints that are given out to send them to the next stage of the quest and then get focused on something pretty much unrelated like a alter or something just put in as decoration. Three of the players are quite new so I'm not sure if it's my DMing or how new they are.
How could I make the game easier for new players to follow while not oversimplifying it?
