A player, 6 January 2012
How does the trait on Hida's Guidance XP interact with cards that straighten multiple personalities at once like Creating Order? As a follow up how would such actions resolve if both players are Crab Clan and both have Hida's Guidance XP in play?
Trait: Before the first straightening each battle of a Personality whose controller’s enemy leader is a Crab Clan player: Negate that straightening.
Creating Order: Battle/Open: Target one or two Personalities: Either negate all current and new Force bonuses and penalties on them from actions, or straighten their units.

The active player chooses which one of the simultaneous straightenings is negated.
See here, specifically this:
"In steps A and B, the active player determines the order of conflicting triggered occurrences as they are happening, not beforehand. The active player must do so in such a way that each of those occurrences happens exactly once. Example: Two personalities destroyed simultaneously in battle resolution, A and B, each have a Reaction or trait that trigger before they are destroyed. The active player decides whether Reactions and traits triggered by A’s destruction happen before or after Reactions and traits triggered by B’s destruction."
