It should have started again now but it is already showing full.
For this week it resets when supply drops do.
The way these kind of chest events work is still whacked. They start at 10am then reset at 8pm (est) then carry on refreshed at 0 untill 10am the next day. Since this event was active yesterday, the limit that started at 8pm last night carries over into today’s event.
It’s not good as we will get less time for the last one
