How does one go about getting replacements for Beginner Box parts that have gone missing? Like, say, the player's book?
You buy a new box. There is no existing part replacement mechanism the way Avalon Hill used to run. Or if you have the pdf, you can print what you need.
Shoot customer.service at paizo.com an email detailing the issue (ie was it missing from the box or go missing afterwards). Hopefully we can take care of you via email.
Thanks! It went missing after opening, so it's not actually the company's responsibility. If the person who last borrowed the box can't find it, I'll shoot CS a message.
