First printing
P. 23 (pdf page# 25), 7th paragraph "Stacking", last sentence:
This is not considered an accidental fall from above.
3 paragraphs down, under "Failed Landing Damage", 2nd paragraph:
Regardless of whether a unit violates Stacking rules for entering a hex, a failed landing roll automatically is treated as an accidental fall from above (see p. 152, TW).
Does this mean a successful landing roll DOES NOT result in an accidental fall from above, but a failed roll DOES?
