On July 29th, August 2nd and August 7th I tried to solve some exercises and I get WA, but I noticed that on the activity map the day was marked with light green color, and I thought it was suspicious because I never got to Accept the problem.
So my question is: is this a bug or am I ignorant of how the activity map works?
Thanks in advance!
