So we started the Living Campaign adventure 'Signals' yesterday, with the crew heading to the surface in a Shuttlecraft. They were blindsided and shot at, and took an incredible 8 damage due to all 4 challenge dice showing the Starfleet symbol, for two breaches. One of the breaches hit the Weapons system, but their shuttle didn't have weaponry.
In this case, do I assume that even a weaponless shuttlecraft has some kind of weapon system (e.g., back-up circuitry that allow for the installation of phasers if they had paid Escalation for those) that absorbed the Breach? Or would we assume there is no Weapons System to begin with, and the damage automatically overflows to Sensors?
I ruled there is a redundant weapons system even in those cases, but want to be sure. (They survived.)
Side question: if they use multiple Arc Milestones in the course of their career, can they theoretically select additional Talents several times?
