I can not explain it. Weird.
These both look like normal battles to me, I cant tell if one is from joyheat or not (but I believe you)
Harra seems like a normal player on offical M11.
I would have to make a Joyheat account to see him there, if there is indeed a Harra with the exact same heroes there, that would be something to investigate for sure!
I will see if I can look into that later, right now I have real life stuff to do.
