In today’s Starters 194, I attempted the “Polygon(subtask here)” and my rank dropped from nearly 232 to 728, and at the end of the contest, it became even worse.
Because my submission time is considered for my attempt on Polygon, which is 2:27:57, but my actual submission time for the correct solution is less than 45 minutes. Even when I got 0 points from this question.
You can see the sudden drop in my graph (attached below), which occurred right after my subtask submission.
I had high hopes of reaching 3⭐ in this contest, but this issue caused a major setback. 
Does this happen for every subtask question that appears in the contest?
