Specifically referring to the 3rd fight in Tombs of Tvericus (sp?). Where there are two 2x2 sections by the victory squares. They are Blocked, can't enter and blocks line of sight, but a Festering Zombies death explosion went right through them to kill two of my party.
I agree that it's a bit odd, but it does correspond to the exact wording of the card: "deal 18 Acid damage to all characters within 2 squares".
