I think I'm facing the same issue. I first sent a program with 1000+ characters.
Then i reached something like 532 characters (that gives me 100%) and rank me 238 but the game still show "Taille du code : 1654" and "519/577" where you select the game you want.
I think the website just keep the first submission results :/
Can somebody check or help me?
I'm quite new here, is there a technical support? or we just ask in the discuss section?
Edit : now it's ok. Don't know if somebody changed something or if the game refreshed by itself... but thanks anyway.
