Week in the Life - 2012 notes

You should have all of the build you have paid for available to be used. So, if you pay upfront on Wednesday for the weekday and weekend portion, you can start utilizing all of that build right away. In other words, as soon as James writes on your card that you have paid for/earned X build, that build is considered added to your "unspent" and "total build" fields on the character card and is available to be spent on learning skills.

I just thought of this question.

The bonus build from doing extra NPC shifts during the week portion. Is that applied to any and all characters you pay for, or do you have to choose one character to give it to?

Bonus Build, other than the specific +1 you can buy at check-in, is always applied to only one PC. Otherwise, people with more PCs are getting more rewards from the same action.
