try to avoid posting solution while you're not logged in, to avoid this kind of situation, next time.

revalidated & cheers

It was Mine Sweeper. I am very sure the solution was mine. Worked on it a couple of hours during a week and didn't look at the solutions either. :)

I'd have to check, but one possible reason is that the submitted solution was recognized as a copy of someone else's solution and points for it got withdrawn.

What kata was that? Was the solution originally yours?

3 days ago I solved a 1 kyu kata and leveled up to 4kyu. Now these points are gone, I am back at 6kyu but the 1 kyu kata still shows up in my solutions. What's happening?
