Just to clarify, we are technically in the round 19 window now (round 20 windows opens at 10pm).
Fortunately, a lot of these last rounds aren't a race for the same all stars but once your window opens you can lap the person ahead of you who did not pick on time.
I messaged some people earlier who were waiting but I think we are basically on schedule now. All but 6 picks are in from round 18 and before.
