There seems to be problems linking my account to WeChall. I can link my account, but the scores says 0%. Is it problem on WeChall or Reversing.kr side?

Reversing.kr tells us you have 0 points, so I'd say if there is a problem, it is on their side.

Dunno why, but when I had 0%, wechall showed that I had solved 10 challenges, even though I had fewer. Everything went normal when I reached 10 challenges.
