Today, I hit 2 banunuramas in the same 3 fight string, the first and third fight. I know I was on a three fight battle, 2 deep, and I let it expire by accident. When I moved again it triggered another PVP fight string with the first being a banunurama. Then, to my surprise, the last fight was also a banunurama. My guess is the third fight of my expired battle was going to be a banunurama, and it just carried over through the time out phase to my next PVP battle string.
Both fights were the same 1 banunu and 2 ikkupi, but I was still stoked that it happened!! Has this happened to anyone else?
