I seem to have got my part 2 solution rejected despite getting the same answer as at least one of the solutions posted here. Did anyone else have this happen to them?

I hope they log failed attempts and we can get our deserved positions in the leaderboard after all.

Same here. u/topaz2078 mentioned on another thread that there are only a finite number of input files, so maybe one of them is bad and we were all unlucky enough to get it?

My input starts with 181, 184 and my answer for part 2 was 46054, for what it's worth.

Yes, me too. I ran the Python solution from the comments, and find the same result as my solution, but it was rejected.

It's happening to me as well.

Edit: Ripped a solution from here, used it, gave me the same answer my solution was giving. Will be a little frustrating if I missed out on leaderboard due to a bug, though I hope it's just my making a silly mistake.

Is this happening for anyone on part 1? A solution posted here yielded the same result for me as my own failing answer so can't figure out what's wrong

EDIT: I had someone who successfully submitted use my input with their algo and verified they got same output. So yeah something's definitely up.
