Final submission
Since there are issues with the site, I just wanted to leave the details on my final submission just in case if something goes wrong with the review.
The submission ID for my final submission is ElNAk7cSSO_7xX, for the source file SHA-256 is E77D1A1759EE603225CBB7A698F751191064FC00BF2395D904BE1E67855C0155. I can see it in 'My submissions' page, but there are no artifacts, and it doesn't seem like even examples would run within the contest timeline.

I think the final ID is: _TpQiBtfBgbCKN, but I don't trust it too much.
Correct ID is: nt_MP5KiE1wAJL
Which is the last file.
