Just want to make sure we are understanding this correctly: when the Triumvirate of Reputation token is moved from the Reinforcement Track to Nova Scotia, does the event have to be used on the immediately subsequent campaign turn, or can it be "redeemed" on a later turn? Section 5.7 states that reinforcements occur on the next campaign turn, but the reason we were unsure is because section 12.1 states "If and when the Crown Player removes the Triumvirate of Reputation marker from Nova Scotia (having moved it there from the Reinforcement Track on a previous turn..." which sounds more ambiguous, such as you might have moved the token but you might choose not to use it, and it might have happened not the previous turn but a previous turn some time ago.
The immediately subsequent campaign turn. The reason why I used "a" previous turn is because a Winter Turn might separate the two campaign turns. Sorry for the confusion. I guess that's why they call it an indefinite article. :-)
