The first 'event card' warns the investigators about the hazard in the freezer, but the investigators can reach the freezer many turn before the first event card is drawn! They have no reason for not exploring the freezer!
And if the objective is not the one with Ithaqua in the freezer, but the one in which the investigators must escape with the 'cerimonial skull', why the investigators have to open the freezer if the 'event card' tells them the opposite? (The cerimonial skull may be in the freezer)
Help me!
Thanks.
