The linked market resolves based on whether 

 passes me in total traders before passing any of the other creators on the Top 20 leaderboard. The leaderboard is supposed to update every 15 minutes, but it hasn't been doing so lately. Instead, it has been freezing, leaving the trader counts unupdated for hours at a time. This could make it unclear whether 

 passed me first, or a different creator, especially since I am in a tight race to retake 19th place before 

 reaches the leaderboard. This market resolves YES if the technical difficulties with the leaderboard make it impossible for me to tell whether I was the first creator slain, if I am forced to resolve based on a reasonable inference that would have been more certain if the leaderboard was updating correctly, or require me to go to much greater lengths to find out than I would have to if the leaderboard was updating normally.
