Global ranking bug

[Quetz]

Ok so me and my friend make a FFA game with 3 bots. He killed 2 bots, i killed 1 + him and after that , we both got 100 points.
replay id is 3888178 (saw it from local archive)
This happened like 2-3 weeks ago. I was looking through the wiki and read about how the raking works. A game with bots should be unrated but still.
Btw this happened when we both had 0 global rank. so this bug may not happen again, also he doesn't want to play so i can't test it again to be sure. =/
