Reward points expiring is new, it starts from today. Points now expire 12 mths after they're earned. Any points accured before 2021 expire today, as per the rewards page on your account. Cut-off is midnight PST, a couple of hours from now. Points accured from 1/1/2021 onwards expire after 12 mths. Not sure how that's going to be shown on the rewards page, it's something I guess we need to keep an eye on since we're earning points pretty much continuously throughout the year with all the different events and weekly shows etc.
As for the events, I don't think there's a schedule for 2022 yet. Last year we had Court of the Dead Day in Feb and Sideshow Birthday in March so those are probably the next couple of events with the potential to earn reward points. Today they did a surprise livestream none of us knew about in advance and gave out $5 in rewards via two lotteries. Always a chance of rewards with the weekly Friday 5pm shows but often they're a waste of time.
