Hi MikeMirzayanov Sorry to bother you. I am having trouble importing my problem from Polygon into Codeforces Mashups. The mashup in question is 549770 and I'm able to import the example A + B problem, but when I try to import my own problem from https://polygon.codeforces.com/p6DUiI7/hstarling/eerie-shadows-ukiepc-test I get Judgement Failed every time I try to submit to it, with the error Can't get problem for submission with id from repository. For example see submission 280973549. I see that someone else had a similar problem on https://www.reddit.com/r/codeforces/comments/1ffgfuk/issue_uploading_a_problem_from_polygon_to/. Is there a general problem with Polygon or are we just doing it wrong? Hopefully you can help, Thanks
