Also, I just noticed something else that makes me think letting it roll is the right thing. I cannot see anywhere in the rules where it says you earn an XP on a miss (which again, I just assumed from my Dungeon World acculturation). If you are only earning XP from mission and personal directives, letting it trigger more than once per scene seems like no big deal to me.

EDIT: I am always making assumptions about rules instead of actually reading them. On my “biggest flaws as a GM” list.
