I don't think this was the case before, but as of right now, my reporting of book 1 of Age of Ashes is showing me as already having received credit and pointing to book 2 as the duplicate credit. Who should I reach out to correct this?

That said, you should still have received AcP (and your character should still have received Reputation), so it probably doesn't actually negatively affect you.
