After a day's thinking and came up with some "cheating" idea, I wrote an answer to this challenge, but here is what I got:

4 test(s) passed
'......' is incorrect.

There are totally 4 tests, so why it didn't accept my answer? Is there a bug or something?

fwjmath.

AFAICS there are 5 tests.

I've had similar problems with the site just saying my program is incorrect on Flash Flood - I assumed it was due to exceeding the cycle count limit. But programs like "0c" and "04-g" on Mus Minutoides cause explicit cycle count exceeding errors, while in Flash Flood they just tell you your answer was wrong.
