Question for anyone who has the MM Rogue One Death Star: Is yours missing a piece? There's apparently supposed to be a fold-out support for the flip-down walkway (which the instructions show being shot out with the missile launcher to make the walkway collapse). Anyway, mine is missing this fold-out support. The instructions don't say you need to attach this support so was it supposed to be factory installed? And on a related note, is Hasbro as good as LEGO when it comes to replacing missing pieces?
