AdjDX & Initiative in ITL

[Kelroy]

In "In the Labyrinth," it says on p102 under Actions, "Figures act in the order of their adjDX, highest first. If figures have the same adjDX, those on the side with initiative go first. Further ties are resolved by die roll."

However, in both the regular rules for Melee and Wizard, it says, "Figures attack in the order of their adjusted DX, highest first; ties are resolved each turn by a die roll," with no mention of initiative.

Now, I realize that ITL is an expanded version of Melee and Wizard, but it seems odd to me to leave it out of those two. Because it very much can change how a fight goes. And it surely couldn't have been left out due to space issues.

I also realize it's not really a big deal, and easily fixed as a "house rule." I'm just wondering why they didn't codify the rules so there would be no discrepancy like this. "Let's play The Fantasy Trip!" "O.K., which one?"

What am I missing?
