A while ago, I had a some but not all of my matches completed in an event called Quick Draft Strixhaven. I stopped playing for a week, and when I came back, the event had disappeared. I think I got rewards for the matches I did play, but I was unable to finish my unplayed matches.
More recently, I saw that the equivalent event for Adventures in the Forgotten Realms was ending, but this time it had a timer counting down with something like "32:16:27". I'm assuming that this timer shows up as the event is within days of closing (48 hours?)
I sometimes leave a draft unfinished for a week until I can come back to it the next weekend. In general, how can I know when an event is going to end? Is there any way to know about this in client, or do I need to look somewhere online?
