The recent change to how Prerelease codes are gone in lieu of event participation is bugged. I attended my local event but had to leave early due to personal reasons and assumed that having my information logged in and having done 2/4 of the games would suffice for online prize redemption. That was not the case, and my account was not credited.

People have things come up, and when they pay for and attend the event, they should not be penalized.
