c-and-j's blog

I noticed some paricipants commenting "Where is my problem X?" and feedbacks like this blog after Codeforces Round 921 (Div. 2) finished system test. Then I investigated their submissions during the contest, and finding their last "Pretest passed" submissions remain untested by main tests AFTER the contest. Pretest passed submission

More such submissions can be seen by filtering all "Accepted" submissions during the contest and sorting by judging time. More submissions

Is there any reason for this?

UPD: It seems to be fixed.

I have just submitted my solutions to 691D - Swaps in Permutation from Educational Codeforces Round 14. They are 19226396, 19226642 and 19226815.

Test #2 is

1 1
1
1 1

I ran my solutions on my machine, compiled with standard command line (g++.exe -static -fno-optimize-sibling-calls -fno-strict-aliasing -DONLINE_JUDGE -lm -s -x c++ -Wl,--stack=268435456 -O2 -o D.exe D.cpp). They all output 1. However, they all got RTE on Codeforces online judging system.

Is there a bug on Codeforces or are my solutions wrong?
