Something definitely happened last night.
I had reviews at 02:00, and decided to stay up. However, when the hour reached 0200 my reviews were still locked, and I had to wait for a whole other hour. And so I waited. When the clock reached 0300, time lapsed back to 0200 and then I could do my reviews. I was very confused as for why I had to wait for the hour to reach 0200 twice, instead of just unlocking my reviews right away @.@
I’m wonder whether this did anything to my overall “time on level”
