Cross-fire, Flanking Fire

[plloyd1010]

As my cousin and I fumbled in the Cuban jungle, we noticed that the Flank Fire rule says [direct] fire traced through non-adjacent hexes. Looking back at all 3 versions of PG rules, they say the same thing in regard to Cross-Fire. This technically creates an interesting issue. If fire needs to be traced through a hexes, as the rule says, cross or flank fire could not be initiated if either the first of subsequent shooters were adjacent to the target. Did anyone else ever notice that?

Incidentally, we play the rule as non-adjacent hexside.
